Campaigning is different from governing.

Sergeant first class Cory Remsburg never gives up and he does not quit.

Your kids grow up. I think they more than anything are making me feel as if, you know, you want to squeeze everything you got every single day out of this thing. Because it passes quick.

I believe marriage is between a man and a woman. I am not in favor of gay marriage. But when you start playing around with constitutions, just to prohibit somebody who cares about another person, it just seems to me that's not what America's about. Usually, our constitutions expand liberties, they don't contract them.

If you want to know who we are, who America is, how we respond to evil-that's it: selflessly, compassionately, unafraid.

How you staff, particularly the chief of staff, the national security adviser, your White House counsel, how you set up a process in the system to surface information and generate options for a president, understanding that ultimately the president is going to be the final decision-maker. That's something that has to be attended to right away.

I know that campaigns can seem small, and even silly. Trivial things become big distractions. Serious issues become sound bites. And the truth gets buried under an avalanche of money and advertising. If you're sick of hearing me approve this message, believe me - so am I.
