New Obama Ad Uses McCain's Own Words About Supporting Bush
The Obama campaign has a new TV ad in response to John McCain's "Original Maverick" ad, rerunning a video from 2003 of McCain himself boasting that he's voted with President Bush more than 90% of the time:

Obama Campaigning With Evan Bayh In Indiana Today
Barack Obama is holding a town hall event today in Elkhart, Indiana, with the focus on energy issues. Accompanying him at the event is Senator Evan Bayh, whose name is enjoying a lot of media attention as a potential vice president -- indeed, this very event has been the cause of some speculation that he would be announced as the running mate.

McCain Visiting West Virginia And Ohio

McCain Camp: Paris Hilton Supports Us On Energy!
The McCain campaign has responded to Paris Hilton's Web video from last night: "It sounds like Paris Hilton supports John McCain's 'all of the above' approach to America's energy crisis - including both alternatives and drilling. Paris Hilton might not be as big a celebrity as Barack Obama, but she obviously has a better energy plan."

Obama Camp Targeting Florida Voters Right At The Gas Pumps
Talk about targeting an ad: The Obama campaign will be running this ad, which was first rolled out yesterday, on a network of TVs that are placed on gas pumps throughout Florida. The ad tells viewers that John McCain isn't to be trusted on energy issues, because he's been around for 26 years and hasn't gotten anything done:

McCain: I Don't Disagree With Obama On Tire Pressure
John McCain is apparently backing down from his campaign's mockery of Barack Obama's call for Americans to keep their tires inflated. "I don't disagree with that. The American Automobile Association strongly recommends it," McCain said last night -- though he added that it's still not enough.

Michigan Congresswoman Kilpatrick Narrowly Survives Primary
Congresswoman Carolyn Cheeks Kilpatrick, mother of the scandal-plagued Detroit Mayor Kwame Kilpatrick, narrowly won her re-election battle in last night's Democratic primary. Kilpatrick won 39% of the vote over her closest challenger's 36%, with the fact that the opposition was split with another candidate almost certainly making the difference.

Poll: Dem Ahead For GOP-Held Seat In Ohio
A new SurveyUSA poll shows the Democrat narrowly ahead for the open GOP-held 15th Congressional District in Ohio: County commissioner Mary Jo Kilroy (D) 47%, state Sen. Steve Stivers (R) 44%. Kilroy previously ran in 2006 and just barely lost to incumbent Congresswoman Deborah Pryce, who announced her retirement last year.

You may not have noticed, but there are actually some key primaries going on today in a few states -- and the results will be coming in tonight. Two races in particular bear watching:

• In Michigan's 13th District, a safe Dem seat, the scandals facing Mayor Kwame Kilpatrick could end up spilling over and ruining a big name in local politics: His mother, Congresswoman Carolyn Cheeks Kilpatrick, who has staunchly defended her son in the local press.

A recent poll from Michigan firm Epic/MRA shows Kilpatrick just narrowly ahead in a three-way primary: Kilpatrick 33%, former state Rep. Mary Waters 29%, and state Sen. Martha Scott 24%. If Kilpatrick does win, it will only be because of a divided opposition.

• In Kansas' Second District, Republican voters will be picking the nominee to go up against freshman Dem incumbent Nancy Boyda, who is among the most endangered Democrats this cycle. The two choices are right-wing former Rep. Jim Ryun, who Boyda defeated in a big upset in 2006, or the more moderate state treasurer Lynn Jenkins.

This race has become a major battle between the state GOP's moderate and conservative factions, and these things are never pretty. For example, the local chapter of the centrist Republican Main Street Partnership put out a press release attacking Ryun, charging that by aligning himself with the Family Research Council and its head Tony Perkins, Ryun was effectively in league with David Duke and the Ku Klux Klan.

The polls close tonight in both states at the same time: 8 p.m. ET.
