The GOP-aligned American Crossroads has reserved $1.1 million in North Carolina ahead of the state's competitive primary, a sign they're looking to boost establishment GOP pick Thom Tillis.
Crossroads Political Director Carl Forti confirmed the buy, but wouldn't discuss whether the group aims at bolstering Tillis in the race.
"We can confirm $1.1 million reserved in Raleigh and Charlotte starting April 1. No comment at this point on the content [of the ads]," Forti told The Hill in an email.
Tillis, the North Carolina House speaker, is battling physician Greg Brannon (R), a Tea Party favorite, and a number of other GOP candidates in the race. He needs to win 40 percent of the vote to avoid a primary runoff, and the few public polls on the race have shown him to be well short of that mark even though his is the only candidate who's been on the air with ads.
Establishment Republicans have been pulling hard for Tillis in the race, seeing him as their best chance to defeat vulnerable Sen. Kay Hagan (D-N.C.) in the GOP-leaning state. Karl Rove, one of Crossroads's founders, has headlined fundraisers for Tillis, as have Senate Minority Leader Mitch McConnell (R-Ky.), Sen. Richard Burr (R-N.C.) and a number of other Republican power players.
