A better indicator is whether GOP candidates shun Trump.
Hes popular and fake news ignores it. Watch the well-attended Iowa rally tonight.
Its a more reliable barometer than the fake polls of how things are going.
I think that the politicians have figured it out, we won’t see much shunning from now on except for the odd idiot like Kasich. The question is, have the voters figured it out. Certainly the GOP have done so, but the key to victory are the sunshine Republicans and Independents.
