“Amen. Run for mayor and give Bloomberg a run for all of his money.”
That would be good. He will have a lot of appeal locally, I would think. Nationally he would probably be about where Giuliani was.
However, if Romney gets the GOP nomination through some fluke similar to ‘08, I would vote for Trump in a heartbeat as a third party candidate. Either DT or BO would win with about 36% of the vote. With his racist base, it would probably be BO, alas.
He’d probably make a good mayor - and as you say - he’d have the same problems with the Republican base that Guiliani had.
