Sorry about the title..I have a thing for alliteration! That aside, tomorrow is the Pennsylvania primary, in which progressive Congressman Joe Sestak challenges Republican turned Democratic Senator Arlen Specter for the Democratic party nomination. Sestak is on a roll.  According to  The Washington Post, Sestak is surging and, according to Bob Schieffer, the White House is preparing for a Sestak win! In case you missed it.. I guest-hosted the Randi Rhodes Show on Friday, and Joe Sestak was my guest.  Click here (or on the player at the top of the post) to hear our conversation.
