I think it's important that when we're running for the highest office in the land, that we recognize that we're living in dangerous times and we have to be serious about it, that our words have consequences.

I will tell you that I'm the only Republican that was in office when he was in office, as president, that never disagreed with him. And I'm not going to start now.

We need somebody with a steady hand being President of the United States.

He's not going to win the nomination because he's not a serious candidate.
