Rasmussen's second look at the Illinois Senate race finds a deadlock, with 41 each for Rep. Mark Kirk and state treasurer Alexi Giannoulias. That's a slight improvement from August, where Kirk had a 3-point lead against the backdrop of the summer of screamers, but it still presages a hard-fought race. (One indication that Rasmussen may be looking at a rather pessimistic sample here, though: Barack Obama's approval rating is 56-44, barely above his national average, in his home state.)
Kirk fares a little better against the lesser-known Democratic candidates who, absent a Giannoulias flameout, don't seem likely to make it out of the primary: former Chicago Urban League head Cheryle Jackson and former Chicago Inspector General David Hoffman (who is polled for the first time). But Kirk never rises above 43%, suggesting that, alleged moderation notwithstanding, he may have something of a mid-to-upper 40s ceiling in this increasingly Democratic state. Along those lines, Kirk's hope seems to lie with independent voters; right now, he's leading 52-23 among the unaffiliated, and he'll need to nearly run the table with them in order to get over the 50% mark.
