They meet again, this time in St. Louis, Missouri. Bush and Kerry take the stage tonight on the campus of Washington University for a town hall-style meeting.

Polls show that Kerry took the first round. In the six days since that encounter, both sides have come out swinging hard. And in those same six days, there has been news from Iraq that is not good. Saddam did not have weapons of mass destruction, but apparently he wanted them. Both of the presidential contenders are using that data to make their cases.

In contrast to the first debate, the voters will be the ones asking questions tonight. Healthcare, education, and the economy are expected to be on the docket tonight.

Tune in tonight as we preview the shifting terrain of the St. Louis debate.
