I’m afraid Rand will become a spoiler in the Republican primaries, perhaps for more than one presidential cycle.
He’ll be among the top three or four vote getters for candidates considered to be conservative, but will have no chance of winning due to his out there libertarian views on several issues. He’ll take enough votes from the one or two most competitive conservative candidates to prevent any conservative from defeating the top RINO.
And he’ll probably keep running primary after primary like his father did.
Conservatives definitely need a way to reduce the field of conservative candidates before the primary voting starts or it’ll probably be another vote splitting scenario that allows a RINO to win.
You are so right: Paul will appeal to non-conservatives who think they are “conservatives”.
