TPM Track Composite: Obama Held Significant Lead Going Into The Debate
Here's our daily composite of the five major national tracking polls. Going into last night's debate, Obama's significant lead over John McCain was holding steady:
• Gallup: Obama 52%, McCain 41%, with a ±2% margin of error, compared to a 51%-42% Obama lead yesterday. At 11 points, this is Obama's widest lead in the Gallup poll for this whole campaign so far.
• Rasmussen: Obama 51%, McCain 45%, with a ±2% margin of error, compared to a 52%-44% Obama lead yesterday. That number from yesterday was Obama's all-time highest lead in Rasmussen.
• Hotline/Diageo: Obama 45%, McCain 44%, with a ±3.3% margin of error, compared to a 46%-44% Obama lead yesterday. Note: This poll's partisan weighting a few days ago was 41% Dem to 36% GOP, but has been changed to 40% Dem and 38% GOP.
• Research 2000: Obama 51%, McCain 41%, with a ±3% margin of error, compared to a 52%-41% Obama lead yesterday.
• Zogby: Obama 47%, McCain 45%, with a ±2.8% margin of error, compared to a 48%-45% Obama lead yesterday. This is the second day for Zogby's daily tracking poll, and the first day that we're including it in our TPM Track Composite.
Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 49.7%-43.2%, compared to a 50.2%-43.2% Obama lead yesterday. Bear in mind that this polling is all from before last night's debate. As such, it does not tell us about the post-debate race, but instead provides us a baseline against which we can measure polls over the next few days.















Hotline/Diageo is really becoming ridiculous!

Ditto that. Research 2000, which does polls for DailyKos, is broken down thus:
Democrats 389 (35%)
Republicans 281 (26%)
Independents 332 (30%)
Last I heard Gallup, Ras, and most of the other so-called "reputable" polls are broken down more or less similar to this, so why is Hotline pushing ten points' worth of independents to the other two columns (mainly to the GOP side)? Can we shitcan a few of these biased polls at some point, so we can get the good numbers we used to get?

Is anyone concerned about the Zogby poll with the numbers at 47/45? What happened there? Are the dumb stupid people breaking for McSame and SheBush for 4 more years like the last 8? What is going on there?

Eric, Clearly Obama has fallen below the 50% mark. Doesn't this indicate the beginnings of a long torturous slide culminating in the ultimate loss of the general election? Or do ya think BO will claw up and manage to cling to whatever 15 point shred of an advantage he'll have by Nov. 4th?

Eric:
Better check your statement about Rassmussen. Since when does a 6 point lead become 'the largest ever in Rassmussen' when the previous day's lead was 8?
Better edit this entry!

Greg I think you guys should just stick to Rasmussen and Gallup.
Zogby = He has not got a single thing right in 8 years (President John Kerry, Obama wins CA and PA in Primary, etc.)
DKos = drastically oversamples Dems
Hotline = drastically undersamples Dems

I was thinking the same thing about Zogby.
I totally ignore them... unless they're telling me what I want to hear :-)

Agreed. Including Zogby in the average totally corrupts the validity of the final numbers.

It's better to keep them all. They're all professionals, who really knows who's right. An average of all legitimate polls is our best estimate. Worst case, if the Hotline/Diageo and Research2000/DailyKos polls are biased in opposite directions, they'll just cancel each other out. They still should help track changes, as long as the bias remains constant.

Eric, do you mean yesterday's 8-point lead in Rasmussen was his biggest so far in that poll?

Yeah, the Gallup and Rasmussen polls are unreal. If I were a McCain volunteer I'd think about calling it a campaign.

from ben smith's politico:
Off message in Pennsylvania
My colleague Amie Parnes reports that Bill Platt, GOP chair of Lehigh County, just warmed up the crowd and referred to Obama as "Barack Hussein Obama" twice, a use the campaign had to disown last week.

Why doesn't the Obama campaign refer to McCain by his full name - John Sidney McCain III,/B>? Sounds just a tad elitist, no?

What about the other polls partisan weighting? I know there are more dem RV, but perhaps this weighting is more accurate? Anyone know Hotline's reasoning for the change?

Thanks for the explanation of the problem with the hotline poll. Do they give any reason for their party affiliation numbers?
I was looking at state polls a while ago. The only "battleground state" giving Obama any real trouble is Indiana. The election could be a landslide of giant proportions. It might even be outside Diabold range.

This warms my heart. In the Research 2000 poll, Palin is at minus 14 in net favorability, her all-time low -- and down 4 points since the VP debate.
Biden is +26, up 7 points since the VP debate.
Hey Pat Buchanan, want to explain again how she wiped the floor with Joe?

What the hell is the use of a tracking poll if they keep rejiggering the party IDs so that one day's numbers aren't comparable to the next's? How is that "tracking"?

Just to join the party poopers on this national poll aggregate, the best poll analysis I've seen uses state poll data to calculate likely electoral votes.
http://election.princeton.edu/history-of-electoral-votes-for-obama/
I realize its not the same thing as a national poll - which is more of a snapshot of overall trends - but it gives a more realistic picture of what the election would look like if held today.
And with more frequently updated state polls the closer we get, the more current it becomes.

Pat Buchanan was for his opinions before he was against them. He jumped up and wet his pants calling Palin a clear winner in last week's debate. After the insta-polls came in overwhelmingly for Biden and Maddow and Olbermann wore him down Buchanan claimed it was a minor victory or something like that.

Zogby... hahaha!!, drop it.
Hotline... Looks like they are moving back to D+5 so I suspect tomorrow should look better for the big O. A good JM is going to fall off tonight I believe.

The National Journal reports that the polling shows a tightening of the race because voters aren't convinced Obama can handle the economy:
The fat lady isn't singing, at least not until she trusts Barack Obama's economic stewardship.
Three polls released so far this week show the race has tightened over the last few days. Obama still leads John McCain in virtually every national survey, but his cushion is shrinking. Tuesday's Hotline/Diageo daily tracker poll gives Obama a 2-percentage-point lead. A Reuters/C-SPAN/Zogby poll also out Tuesday pegs the Illinois senator's advantage at 3 points. And a CBS News poll [PDF] released Monday gives Obama a 3-point advantage among likely voters.
There are plenty of polls out this week still showing a big Obama advantage, such as the Gallup Daily tracker, which shows the Democrat with a 9-point lead, and Rasmussen's horse-race poll, staking him an 8-point advantage. But there are other numbers buried in the data that don't portend well for Obama.
Obama's advantage over McCain on economic stewardship has been inching downwards in recent days, and Tuesday's Hotline/Diageo poll shows the two candidates tied at 42 percent over who would best handle the economy. That advantage was 9 points for Obama as recently as Oct. 3.
McCain's gains may have less to do with any policy proposal by the Arizona senator than with Obama's inability to convince voters he can run the economy.
I realize that Hotline has modified its party identification mix but presumably they had some data to back this up. can anyone enlighten us here on this?
I have never been one to think this would be a ten point race even with the economy tanking. at best, the ultimate vote would be a 53-47 Obama win. so are we seeing only numbers that reflect a different weighting based on party mix and if so, why the change? are we seeing the inevitable tightening of the race and, if so, isn't this a little early to occur? or are we really seeing voter concern about Obama's ability to address the issue and, again if so, is this really a "cloak" for racism?

You should weight the polls by sample size NOT by the square root of sample size. Consider this reductio ad absurdum case: one poll has two votes for Obama, none for McCain; the other has one vote for McCain, none for Obama. The answer you want is simply 66.67%, nothing to do with the square root of two...It is true that the margin of errors are (inversely) proportional to the square roots, but that's not the issue here.

Yes, I was going to post the same comment myself.
I think previous days have reported weighting by sample size. Was there a change in weighting, or just a garbled explanation?

Zogby hasn't been correct about anything in recent history. Why is it still around?
October 8, 2008 2:03 PM | Reply | Permalink
Eric - Zogby polls are a joke. The evidence of this is their horrendous track record which speaks for itself. I don't think including them in the composite is a good idea.
Hotline - inexplicably changed party ID from +5 democrat to +2, hence the sudden fall in the spread between Obama and McCain in their polls. What valid reason there could be for that, I have no idea when it has been established there is at the very least a +5 advantage in terms of registered voters for the democrats over republicans. They are oversampling republicans without providing a valid reason for doing so.

This daily average should also include the Battleground (GWU) tracking poll (currently O+4)which has been around for years unlike the new Kos tracker. The KOS 9-point Dem ID margin is bigger than the 6-point margin in Rasmussen and I think the biggest of any tracking poll.
October 8, 2008 3:29 PM | Reply | Permalink
Zogby - Meh!
Hotline - OK until they switched their party ID to a ridiculous +2 Dem.
R2K - Oversamples Dems a bit but I like that Markos posts the full internals and the individual results for each day. Don't get that from the others.
GWU/Battleground - Much better since they changed their weighting model. Remember when they had McCain +2 just about a week and half ago?
Gallup - I don't think they weight for party ID. And they seem to often fall vicitim to short-term surges, probably as a result of their weighting problem. Remember when they had Obama +9 during his Europe trip and it swung back to a tie in less than a week?
Rasmussen - He's a wingnut but his daily tracker is the one I trust the most. We can't see his internal data (at least not without a subscription) but his party ID weighting seems pretty close to reality (Dems +6), he adjusts it weekly, and he has a pretty big sample size with a relatively small MoE. One thing I've noticed during this entire cycle - his poll is the most stable - it's not as susceptible to the event-driven swings. It does take them into account if they have a lasting effect, but it shifts gradually, not like Gallup.
If Rasmussen starts to dip below +4 Obama for any length of time, then I'll start to worry. But as long as he's showing +4 Obama or higher - especially if Obama is at 50 or higher - I'll sleep pretty well at night.

this from charles Franklin at pollster.com on Monday and food for discussion:
So here is a question to ponder. How much more upward lift can there be for Obama? He's already well beyond his previous best. Does anyone believe he really can hold a 10 point lead through the election? If not, then we should see some flattening out in the next few days, regardless of the debates.

I will not be surprised if a surrogate somewhere - publicly - whips out "nigger". I think they're dangerously close to crossing over that line.
I love how the folks on The Corner - in the current Ayer obsession - are now saying that what Americans need to know is that Obama is far out radical. Problem for them is that a) he isn't and b) Americans don't see him that way - and contrary to what Jonah and Andy and K-Lo would have you believe, the American people do know Obama, probably better than any politician in the country. But if Obama is a radical, what is Palin? And at whose rallies are people yelling death threats, accusing people of treason, intimidating the media, blowing racist dog whistles, and calling black people "boy"? Seems like a number of the fans of The Corner's favorite gal are pretty fucking nuts.

The Intrade swing today is the largest I've seen yet. An 11.5 gain for the big O.

Look folks, all Daily trackers suck. The only reason we are paying so much attention to them now is because they are helping the narrative and have O up higher than he has ever been. However, at the end of the day they are just nice to look at, but don't tell the real story of this election.

Cindy McCain calls Obama's the "dirtiest campain in history".
Obama may have bought a $3 million projector.
But McCain is married to a $100 million projector.
Now...
Let us reflect on the gift that Sarah Palin has given us all:
