Mark Udall, meet Bob Perry.
Udall, a Democratic member of Congress from Colorado, is running for Senate this year in a race that is attracting out-of-state money from all sides.
Perry, a Texas developer, gave $4.4 million to Swift Boat Veterans for Truth to help defeat John Kerry in 2004. FEC reports reveal that the Texan dropped $400,000 this month to air an ad criticizing Udall for "wasteful" spending.
Perry gave the money to the Club for Growth. The group said in a press release that the ad will be up for 2 weeks.
