I'm tired of dealing with the crazies.

I would not compromise my principles for politics. You're saying, will it become politically unpopular to have the position I'm having? If it does, so be it. I don't compromise my principles for politics.

Today, the biggest challenge we must meet is the one we present to ourselves. To not become a nation that places entitlement ahead of accomplishment. To not become a country that places comfortable lies ahead of difficult truths. To not become a people that thinks so little of ourselves that we demand no sacrifice from each other.

Donald Trump wants to look at this situation [with immigrants] and deal with it in a humane way, and quite frankly, you know, I think this is the kind of thing people expect from a president of the United States.

Well, let me tell you, after three years of Obama, we are hopeless and changeless, and we need Mitt Romney to bring us back, to bring America back.

That's why I call Barack Obama a petulant child. He's doing it on guns. He did it on immigration. He's done it on "Obama care."

Since the president's [Barack Obama] lost all of that [majority in Senate], he now has decided he's just going to write laws on his own. He's going to give us edicts, as if he's a king. And that is a petulant child. He's refusing to listen to the will of the American people, which is they reject his policies.
