The last two months have not been good for Alexi Giannoulias, and Mark Kirk now leads him 37-33 in his bid to be the next Senator from Illinois.

A PPP survey taken a week and a half before the primary found Giannoulias up 42-34 on Kirk. But the closing stretch of the campaign did not go well for the Democratic nominee, with the attacks on him resulting in a final margin of victory that was a good deal less than what he had shown in earlier polls. Since then most of the news for him has been bad.

The main reason Giannoulias is behind is that he’s getting only 54% of the Democratic vote while Kirk is winning 77% of the Republican vote. It’s not that a lot of Democrats are planning to cross over and vote for Kirk, but 36% of them are undecided right now compared to just 16% of Republicans. That suggests Democratic voters don’t really know what to make of Giannoulias’ problems right now so they’re just taking a wait and see approach to the race.
