Calling it "a massive one-week ad blitz," the liberal group VoteVets.org has gone on the air against Sen. Susan Collins (R-ME). Here's the ad, which challenges Collins' role in overseeing U.S. spending in Iraq.
Collins is a moderate Republican. Her challenger, Democratic Rep. Tom Allen, has a strategy of tying her to President Bush. This ad subtly helps that effort, although it only mentions the president once.
VoteVets says the ad will run Friday through Thursday, at a cost of $200,000.
