PHILADELPHIA (AP) -- Armed with talking points and front-runner status, Hillary Rodham Clinton is preparing to defend herself in tonight's Democratic presidential debate in Philadelphia.
It's the Democrats' first debate in a month, and during that time the New York senator has gained in the polls and taken the lead in fundraising.
Barack Obama has attacked her for a vote on Iran and for failing to explain how she would save Social Security.
John Edwards is questioning her honesty and integrity, an area in which polls show voters are divided on Clinton.
The Clinton campaign has responded by posting videos of Obama and Edwards saying they would campaign on hope, not by tearing down their opponents.
