NEWT GINGRICH: There's no reason for the underdog team to quit -- They should play out the end of the game. But there comes a moment and for Trump it may come as soon as Tuesday night. If he wins Indiana, I was telling him a little while ago, John Hines was telling me there’s a new poll that puts Trump up by 15 points in Indiana, if that’s true and he wins Indiana by a significant margin.
Then the fact is the next morning he is the nominee. Not the presumptive nominee, he’s the nominee. It’s going to happen.
