If it's past the primary, RINOs absolutely deserve our vote. It's about the caucus, not about purity. It's about winning the Trump agenda, not about principle.
As for being 20 points down, how do you think a dynamic, well-spoken guy like John James will do in Detroit? Against a tired old bag like Debbie Stabenow? Admittedly, she does have a D after her name ...
I have James as the longest of shots, with less chance than Vukmir or Barrasso.
