A pro-Democratic super PAC launched an ad in favor of vulnerable Sen. Claire McCaskill today. Majority PAC's ad, titled "Them," follows the same messaging previous pro-McCaskill spots have used: attacking outside groups that are targeting the Missouri Democrat.
"Why are the corporate special interests attacking Claire McCaskill?"asks a male narrator in the spot. "Because they want to keep getting tax breaks when they ship our jobs overseas. And Claire McCaskill is determined to stop them."
The ad is backed by a two-week, six-figure buy in the Kansas City and St. Louis media markets.
McCaskill will face the winner of a contentious GOP primary between Rep. Todd Akin, former state Treasurer Sarah Steelman and wealthy self-funding businessman John Brunner.
Roll Call rates the Show-Me State's Senate race a Tossup.
