I need to be very careful about going on certain networks that seem to have a bias.

I went to my first national convention in 1976, when my family supported [Ronald] Reagan over [Gerald] Ford, so we've always been Republicans, but we've always wanted the Republican Party to be the party of fiscally conservative, limited-government types. And I think, sometimes, we haven't done that as well.

Any time you make an analogy to horrific people in history, Mussolini or Hitler, people say, 'Oh, you're exaggerating, you're talking about, it's hyperbole.' Maybe it is. ... But I would say is that if you are not concerned that democracy could produce bad people, I don't think you're really thinking this through too much.

The Bill of Rights existed long before President Obama was elected, and as long as I’m a U.S. Senator, I will fight to protect the basic rights and liberties that belong to all of us as American citizens.

Unless you really stand for something, people aren't motivated to go out and vote for you.

The GOP of old has grown stale and moss-covered. I don't think we need to name any names, do we? Our party is encumbered by an inconsistent approach to freedom. The new GOP will need to embrace liberty in both the economic and the personal sphere.

I think Republicans will not win again in my lifetime ... unless they become a new GOP, a new Republican Party. And it has to be a transformation. Not a little tweaking at the edges.
