If that happens it could be serious trouble for the President
Balderdash.
The Never Trump Republicans are leaders without followers. Evan McMullin, David French, Bill Kristol - they cant get 100K votes between them.
So you can't imagine Soros,Steyer,Zuckerberg and SEICU giving tens (or hundreds) of millions to the mailman's son knowing that the Rat nominee can't beat the President but that Kasich can take enough votes from him in PA,OH,MI and WI to hand those states to the Rat?
I can imagine those states coming out:
Trump-40%,Mailman's Son-15%,Rat-45%
