The National Republican Senatorial Committee will go on the air in Arizona, marking the first time the committee has gotten involved in a race that was once considered a slam-dunk for Republicans.
But national money has recently started pouring into the race in Republican-leaning state, where several polls are showing a dead heat between GOP Rep. Jeff Flake and his Democratic opponent, former U.S. Surgeon General Richard Carmona.
The Democratic Senatorial Campaign Committee launched a $526,000 ad buy in that state this week -- their first commercial in the contest today, going after Flake on women's issues. And Democratic outside groups VoteVets.org and Majority PAC made a $280,000 buy. On the Republican side, the Club for Growth announced a $500,000 buy in the state this week.
Meanwhile, Carmona announced raising an impressive $2.2 million in the third quarter -- no word yet from Flake.
Politico first reported the NRSC's Arizona ad buy.
