I wonder what he considers a viable path??
the path he needs to be concerned with is back to Texas where he can look for a real job.
The convention not having selected a nominee.
He's mathematically eliminated now, and still sees a viable path to the nomination. I don't see why having a presumptive nominee would necessarily cause him to have a change of heart.
Gut-check time for the RNC comes for sure on June 7th. I don't picture the Bush or Romney families allowing the party to treat Trump as the presumptive nominee between June 7th and the convention. Their heels are dug in, hard.
