If he holds a rally or two there, he would set the place on fire - resurgent Republicans and panicked Democrats**.
Even though he would lose the CA Eectoral votes, I'll bet his coattails would bring in a few more down-ballot Republican Representatives. He's gonna need all the help he can get.
** Can you imagine the pearl-clutching that his announced rally(s) would cause, knowing how big the televised crowds would be?
Yup, and imagine the MSM trying to explain away all the Latinos in the crowds he amasses. Pure torture.
