Hillary Clinton, Michelle Obama to Appear on Colbert

Democrats appearing on The Colbert Report have sometimes enjoyed increases in fundraising afterward. Since Clinton is supposedly having fundraising issues, particularly in comparison with Barack Obama, could this be the reason she's willing to take a chance on appearing on the show?

She's going to have to accept being second however, as Michelle Obama will appear on Tuesday's show.

The Colbert Report is spending the week covering next Tuesday's Pennsylvania primary.

News of Clinton's visit was apparently supposed to be a surprise, but was accidentally divulged on Monday night by MSNBC's Chris Matthews, who blurted it out backstage during taping of his show at the University of Pennsylvania's Zellerbach Theater.
