Twenty-five years ago, I created the Taxpayer Protection Pledge at the federal level. Then I brought it to the state and local level. About 97 percent of the Republicans in the House and 85 percent in the Senate have signed on, and the number of candidates who have taken the pledge is even higher. It's become a party position.

I want to reduce the size of government in half as a percentage of GNP - gross national product - over the next 25 years. We want to reduce the number of people depending on government so there is more autonomy and more free citizens.

People are an asset, not a liability. The United States is the most immigrant-friendly nation in the world and the richest country in the world. This is not a coincidence. Those voices that would make us less immigrant-friendly would make us less successful, less prosperous and certainly less American.

Government should enforce rule of law. It should enforce contracts, it should protect people bodily from being attacked by criminals. And when the government does those things, it is facilitating liberty. When it goes beyond those things, it becomes destructive to both human happiness and human liberty.

We want [government] down to the size to where it would fit in a bathtub, and then it could worry about what we were up to.

Which idiot put the GOP convention the same time as 'Burning Man' in Nevada? Is there time to change this?

The tax issue is the most powerful issue in American politics going back to the Tea Party. People say, 'Oh, Grover Norquist has power.' No. Grover Norquist and Americans for Tax Reform focus on the tax issue. The tax issue is a powerful issue.
