The GOP outside group American Crossroads is officially getting involved in North Carolina's GOP Senate primary, launching ads to back North Carolina Assembly Speaker Thom Tillis (R) over his Republican opponents
Tillis, the establishment favorite, is facing Tea Party favorite Dr. Greg Brannon (R), Rev. Mark Harris (R) and a number of other Republicans vying for the nomination to face Sen. Kay Hagan (D-N.C.).
The ad campaign is Crossroads's second foray into a GOP primary in recent weeks, as it seeks to back candidates it views are more electable in general elections. Crossroads is also airing ads touting Alaska Senate candidate Dan Sullivan (R). The Hill reported last week that Crossroads was buying airtime in North Carolina to back Tillis.
Polls have been all over the place, but he hasn't topped the 40 percent needed to win the primary without a runoff in any of them.
