Obama, Clinton debate as Pennsylvania primary looms

Associated Press - April 16, 2008 6:23 PM ET

PHILADELPHIA (AP) - Wednesday's debate between Barack Obama and Hillary Rodham Clinton will be the 21st of the Democratic presidential nominating contest. It could also be the last.

Clinton and Obama haven't met for a debate in nearly two months. The last time was in Cleveland on February 26th, shortly before Clinton injected new life into her campaign with primary wins in Ohio and Texas.

Since then, there has been tough talk and finger-pointing between the rivals and their campaigns. Both candidates are vying for victory in next week's Pennsylvania primary.

Polls show Clinton leading Obama in Pennsylvania, but the margin has greatly narrowed in recent weeks.

Another debate is possible in North Carolina this Saturday. Obama has accepted, but Clinton has not.
