You might not like what the Democrats are doing, but can anyone actually say they think the Republican party is worthy of public office? It’s like they keep pulling dirty tricks but end up being the ones caught. Potential supporters who oppose Obama & Co. only see jack-booted clowns running the Republican show.

Barack Obama’s most devilish political move since the 2008 campaign was to appoint a Republican congressman from upstate New York as secretary of the Army. This week’s election to fill that vacant seat has set off nothing less than a riotous and bloody national G.O.P. civil war. No matter what the results in that race on Tuesday, the Republicans are the sure losers. This could be a gift that keeps on giving to the Democrats through 2010, and perhaps beyond.

That this pastoral setting could become a G.O.P. killing field, attracting an all-star cast of combatants led by Sarah Palin, Glenn Beck, William Kristol and Newt Gingrich, is a premise out of a Depression-era screwball comedy. But such farces have become the norm for the conservative movement — whether the participants are dressing up in full “tea party” drag or not.

The battle for upstate New York confirms just how swiftly the right has devolved into a wacky, paranoid cult that is as eager to eat its own as it is to destroy Obama. The movement’s undisputed leaders, Palin and Beck, neither of whom have what Palin once called the “actual responsibilities” of public office, would gladly see the Republican Party die on the cross of right-wing ideological purity. Over the short term, at least, their wish could come true.
