Our aim is a democratic peace.

One thing you had to learn [after the presidency] was that you no longer had the sense of responsibility that became ingrained in your system.

Good stewardship of the environment is not just a personal responsibility, it is a public value... Our duty is to use the land well, and sometimes not to use it at all. This is our responsibility as citizens, but more than that, it is our calling as stewards of the earth.

We do not prescribe any prayer; we welcome all prayer.

This will not be a campaign of half measures, and we will accept no outcome except victory.

The people in Louisiana must know that all across our country there's a lot of prayer - prayer for those whose lives have been turned upside down. And I'm one of them.

Other Republican candidates may retort to personal attacks and negative ads.
