Philadelphia is set to play host to Campaign '08 when seven democratic candidates debate at Drexel University on Tuesday night.

It has been more than 30 years since Philadelphia has seen a debate between presidential candidates, but it will be the eighth time the seven leading democratic candidates seeking a shot at the White House have faced off, reported CBS station KYW-TV in Philadelphia.

During the nationally televised debate, candidates are expected to discuss various topics, including the economy, healthcare and the ongoing war in Iraq.

Early favorite Sen. Hillary Clinton will join Sens. Barack Obama, Joe Biden and Chris Dodd, former Sen. John Edwards, New Mexico Gov. Bill Richardson, and Rep. Dennis Kucinich onstage for the debate.

The debate starts at 9 p.m. ET on MSNBC and MSNBC.com. Drexel University will also offer a live stream on its Web site.
