Mitt Romney actually said...

I wish every Republican who supported Mr. Trump said I made a mistake, let's go a different direction.

Oh, I think his comments time and again appeal to the racist tendency that exists in some people and I think that's very dangerous.

There's no question in my mind, he will never release his tax returns.

I wish there had been somebody that stopped Mr. Trump, had I been in the race, I can assure you, I would have taken him on.
