We must do right and risk the consequences.

Running for the presidency's not an IQ test.

I've always believed the mission is greater than the man.

Crucial to understanding federalism in modern day America is the concept of mobility, or 'the ability to vote with your feet.' If you don't support the death penalty and citizens packing a pistol - don't come to Texas. If you don't like medicinal marijuana and gay marriage, don't move to California.

I got all the respect in the world for the front-runners in this race, but ask yourself: If we replace a Democratic insider with a Republican insider, you think we're really going to change Washington, D.C.? You don't have to settle for Washington and Wall Street insiders who supported the Wall Street bailout and the Obamacare individual mandate.

I think you need to have a tax system that basically is flat, fair and simple. And - that you can put on a post card. I mean, even Timothy Geithner could do this one and get it on time.

What I learned growing up on the farm was a way of life that was centered on hard work, and on faith and on thrift. Those values have stuck with me my whole life.
