With Trump’s actions and comments dunking on some of the conservative candidates who lost because they weren’t team Trump, I think he’s increasing the potential number of swing voters as principled conservatives realize they’re not welcome in the current Republican Party.
Flake made a comment this week about somebody needing to challenge in the primaries next cycle. There are too many xenophobes and Trump lap dogs for anybody to beat trump in a Republican primary but it would be really interesting to see how a reasonable conservative candidate like Ben Sasse would do to get a measure of how divided the party really is.
