GOP House candidate Peter Roskam -- you remember, the one who suggested that Tammy Duckworth wanted to cut and run from Iraq, even though she lost both legs in the war -- has just released a new ad featuring all of his kids. They tell viewers that the key thing about Roskam is that he's a "good dad." And one son says "he talks a lot about protecting Social Security, too" -- even though last year as an Illinois state senator Roskam ducked out of a vote on a resolution calling on Congress to oppose private accounts. Maybe Roskam's trying to air-brush his portrait a bit, now that Duckworth is aggressively painting him as callous in the wake of his less-than-tasteful remark. Check it out below.
