The quibble I have with President [Barack] Obama is,and I think some other people will have it, too is that the rhetoric is fine, and identifying the problem is fine. But it`s to use a football analogy, he sort of pushes it into the red zone, and then tends to settle for a field goal.

If American workers are being denied their right to organize and collectively bargain when I'm in the White House, I'll put on a comfortable pair of shoes myself.

Historically - when you look at how America has evolved, typically we make progress on race relations in fits and starts. We make some progress, and then there's maybe some slippage.

This is a time of great change in the world but America's always been a pillar of strength and a beacon of hope to peoples around the globe and that's what it must continue to be.
