Charlotte, North Carolina (CNN) - Republicans avoided a major headache on Tuesday night when Thom Tillis, the North Carolina house speaker and establishment favorite, won the Republican Senate nomination outright, dodging a protracted summer runoff fight against a grassroots-backed opponent.
With an assist from big-spending outside groups, Tillis dispatched his two main primary rivals, tea party-backed Greg Brannon and the Baptist pastor Mark Harris, with relative ease, clearing the 40% mark needed to skirt a July runoff election.
