You can't go home and look at your plaques at the end of the day, because every politician has like a million plaques on their wall. OK? You don't go home and look at - you don't get anything for that. And you can't go home and say, boy, I really served the Democratic Party or the Republican Party. You want to go home and, you know, Fourth of July, you know, any of these special holidays that recognize our country, you want to feel like you've built a stronger nation, which means you helped build the people and put them in a stronger place where everyone's lifted.

I mean, I don't have any more words.I've tried to do the best I can to lead by my actions in an appropriate way without recrimination or anything like that, because I'm a very happy person. I don't think I need to say any more than what I've demonstrated.

I worry about America. For the first time in my lifetime, I'm worried about us, i'm worried about how our values to some degree have been eroded, of personal responsibility and compassion and teamwork. I worry about it, I worry about the fact that we're so divided.

I can't work any harder. I can't do any more. I am literally just blown away and humbled by the volunteers and how hard they're working. I think they've got a sense that they're going to be part of something bigger than themselves.

There were 16 people in the race, including a number of governors, and there's only one left. And I think that at the end we have to make sure that we have somebody that can go to that town, change that system, grow employment, change the whole way in which it works and ship power money and influence back to the states. So I'm optimistic about it.

When I listen to candidates spend all their time attacking Barack Obama, I'm glad they're not driving this bus because they'd be looking through the rear-view mirror. I look through the windshield at the road ahead.

This is not about Republican or Democrat. It is about our children, it's about our families, it is about our country, and frankly, ladies and gentlemen, it is about the world. We've got to leave here and march, and make sure Mitt Romney and Paul Ryan are president and vice president of the United States.
