The other day we referenced a poll by Senate Dems which found that GOP Senate leader Mitch McConnell's Iraq positions were out of step with those of his constituents in the state of Kentucky.

Now the DSCC has released some new numbers from the same poll -- numbers it claims show that McConnell's vulnerable to a challenge:

I know it's a long way off, but if next year's election for U.S. Senate were held today, would you definitely vote to re-elect Mitch McConnell, probably vote to re-elect him, probably vote for someone new or definitely vote for someone new?

TotalRe-Elect: 47%

Total Someone New: 44%

Numbers showing support for generic opponents are usually bogus -- people vote for real people in elections, not generic ones -- but the fact that McConnell's support is in the below-50% danger zone could be significant. Keeping in mind, of course, that this is a partisan poll.
