It remains to be seen whether or not this mark represents something of a low ebb for Giannoulias in the wake of a recent flare-up of the cloud of bad press related to his family's bank that continues to dog him -- or whether we can take this as a warning sign of an extremely difficult campaign to come. At the very least, the biggest chunk of undecideds are Democrats:
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.
However, Jensen also adds: "There may not be a state in the country where Democrats have a weaker top of the ticket at this point than Quinn and Giannoulas."
That doesn't bode well for the gubernatorial portion of this poll, which will be released later this week.
