Looks like the "Colbert Bump" may have some significance after all, as both Michelle Obama and Hillary Clinton are appearing on the Colbert Report this week when it's in Philadelphia. The news about Michelle Obama appearing came out a while ago, but the news about Hillary appearing this Thursday was (inadvertently?) revealed by Chris Matthews yesterday. However Variety confirms she will appear.

I missed last night's episode but have it DVR'ed, so stay tuned for more news after tonight.
