After a thirty year career in the Senate, Pennsylvania Senator Arlen Specter was defeated in the Democratic primary by Rep. Joe Sestak.  Specter changed his party affiliation from Republican to Democratic just last year, and Sestak capitalized on the switch by running television ads that accused Specter of becoming a Democrat in order to be re-elected.  Democratic party leaders urged Sestak not to run against Specter; in fact, Sestak has stated that the Obama Adminstration offered him a high-ranking federal job on the condition that he quit the race.

Booman Tribune proposes that last night’s results couldn’t have been better for President Obama or the Democratic Party (any other conclusion is apparently the result of media bias).
