Illinois Senate 2010: Mark Kirk Attacked In New VoteVets Ad

After Tuesday's primary sealed the deal for a Mark Kirk and Alexi Giannoulias face off in November's election for U.S. Senate, the two have wasted no time in going after one another. At least, their proxies haven't.

The morning after the election, the National Republican Senatorial Campaign released an attack ad with an announcer, affecting a New Jersey accent, proclaiming: "Alexi Giannoulias: He'd make Tony Soprano proud."

Now, VoteVets, a progressive political action committee, is striking back. The group released a national ad Friday featuring an Iraq war veteran chastising Kirk for refusing to support energy independence. The veteran suggests that Kirk opposes climate-change legislation because he's received donations from oil companies operating in foreign countries.

Interestingly enough, Kirk was one of only eight Republicans to vote for the climate change bill in the House. But facing primary challenges from the right, he reversed his stance on the issue.

Republicans didn't exactly make him pay for the flip-flop in the primary. But Democrats are clearly hoping to capitalize on the issue in November.
