I can not think of one state Trump would lose that Romney won. Can anyone else?
I can think of several states he might win that Romney lost.
Only Trump has any crossover appeal whatsoever, which is needed to win the presidency. Rubio is the only other contender who had that (just keeping it real). If Trump is denied the nomination, there’s going to be a lot of situations right down to the local level where the ‘pubs will lose badly.
