I don't think [Mitt] Romney can sit there and wait to win because perhaps people are disappointed with President [Barack] Obama.

The media claimed to be non-partisan, centrist. It's not been that way for a lot of history.

In any case, open-seat presidential elections like 2008 just are different in character from incumbent reelects, and I think that's the most important thing about this election - is that once there's an incumbent running for reelection, most of the debate is about, "Has he [Barack Obama] done a good job?" Most of the judgment is, "Do you want to keep him or do you want to replace him?" Now, the opponent has to also be acceptable and has to make his own case.

If President [Barack] Obama - President [Donald] Trump shows up with a, you know, cleaver and just says, I can get rid of all these regulations, I can get rid of ObamaCare, no problem at all, then that would be a mistake.

He should release the tax returns tomorrow. It's crazy. You've got to release six, eight, ten years back tax returns. Take the hit for a day or two. He has to give a big speech in defense of capitalism, and that will elevate, I think, this race above this tactical back and forth, which I do think he's on the margin of losing.

I think that's what's - one of the things that is alarming to me is [Donald] Trump, and I think Trump supporters seem to believe, he won, huge upset, full credit to him, and has got the wind at his back. And Republicans on The Hill do want him to succeed, obviously, and they're deferring to him more than they deep down in private sort of wish - want to, but they are going to defer to him publicly for awhile. But I think that is going to run out faster than people think.

Mitt Romney has to convince the American public that they need to do something they're not usually inclined to do - replace a sitting president with a challenger. And unlike in 1980 and 1992, when the public was persuaded to do just that, the incumbent president has not been weakened by a primary opponent.
