During the debate, which focused on economic matters, Bush went on the offensive. "Hillary Clinton has said that Barack Obama's policies get an A. Really?" Bush asked. "One in 10 people right now aren't working or have given up altogether, as you said. That's not an A. One in seven people are living in poverty. That's not an A. One in five children are on food stamps. That is not an A. It may be the best that Hillary Clinton can do, but it's not the best America can do." Hide Caption 2 of 16

"Thank you for not asking me what I said in the 10th grade, I appreciate it," Carson said. "The fact of the matter is, you know, what? We should vet all candidates. I have no problem with being vetted. What I do have a problem with is being lied about and then putting that out there as truth." Hide Caption 3 of 16

By artificially keeping interest rates below the market rate, average ordinary citizens have a tough time earning interest, have a tough time making money. They're actually talking now about negative interest." Hide Caption 7 of 16

"The problem is that today people are not successful working as hard as ever because the economy is not providing jobs that pay enough." Hide Caption 8 of 16
