Several Democrats have warned newly-minted Democratic Sen. Arlen "Weather Vane" Specter that if he doesn't shed some of his Rethuglican positions, he'll face a challenge in the Democratic primary next year. Former Democratic National Committee chair Gov. Howard Dean and AFL-CIO Secretary-Treasurer Rich Trumka are indicating that Specter's acceptance as the Democrat's Senate candidate isn't a given, especially if he goes against the union-backed Employee Free Choice Act and against Obama's health care proposals. He's already voted twice against the Obama Administration, so the signs aren't good that Weather Vane has a clue about which way Pennsylvania political winds are blowing.
