When you couple this militarization of law enforcement with an erosion of civil liberties and due process that allows the police to become judge and jury - national security letters, no-knock searches, broad general warrants, pre-conviction forfeiture - we begin to have a very serious problem on our hands.

We should understand the limitations of war. We should understand the sacrifices our young men and women go through losing lives and limbs. And they should only do it for the highest of purposes.

John McCain is the guy that has advocated for war everywhere. He would bankrupt the nation.

The Republican promise is for policies that create economic growth. Republicans believe lower taxes, less regulation, balanced budgets, a solvent Social Security and Medicare will stimulate economic growth.

This flirtation with isolationism in the Republican party is over. It's giving way to a more muscular foreign policy than I've been advocating. But I'm also advocating building up others. Build a small schoolhouse in Afghanistan to help a poor young girl have a say about her children will destroy the ideology more than a bomb.

If I had been told to get out of the street as a teenager, there would have been a distinct possibility that I might have smarted off. But, I wouldn’t have expected to be shot.

You can see why there are more people wanting to come from economically-distressed areas, and they can't all come to America. So it gets into the valid, legitimate debate over immigration as to how do we choose. Do we have a diversity lottery and take people from everywhere, do we base it more on merit?
