Poll: GOPer Kirk’s Lead Grows In Illinois Senate Race

The new Rasmussen poll of the Illinois Senate race finds Republican Rep. Mark Kirk expanding his lead over Democrat Alexi Giannoulias in the race for President Obama’s former Senate seat — a sign that the failure of Giannoulias’s family bank could possibly endanger this seat for the Dems.

The numbers: Kirk 46%, Giannoulias 38%. The survey of likely voters has a ±4.5% margin of error. Three weeks ago, before the bank’s closure, Kirk had a much narrower lead of 41%-37% in Rasmussen’s polling. In addition, Kirk’s favorable rating is 52% to 31% unfavorable, compared to Giannoulias’s 42%-47% rating.

The TPM Poll Average for this race gives Kirk a lead of 42.3%-35.5%.
