Politics Is ... Never Having to Say You're Sorry

The candidates were asked to describe an instance where they didn't tell the whole truth about an issue related to their public roles. Clinton used the question to discuss her 2002 vote for the Iraq invasion.

"I, too, regret giving George Bush the authority," said Clinton. "Looking back on it, I wouldn't have voted that way again."

She did not directly apologize for the vote, a stance that early in the campaign had inflamed many on the left. It's worth noting that none of her rivals -- either top tier or second tier -- challenged Clinton on the point.

Edwards answered the question by saying he regretted not discussing his initial reservations about the Iraq vote.
