Sen. Arlen Specter (D-Pa.) seems to have momentarily forgotten which party he belongs to.

In this video, the party-switching senator notes that he has been endorsed by the college Republicans, except that the more applicable endorsement for him right now would be the college Democrats. Whoops.

It's not the first time Specter has slipped up on his new party affiliation. Shortly after the switch, he suggested he was rooting for GOP Sen. Norm Coleman (Minn.) in his recount effort.
