Coaxing Arlen Specter into switching parties and running for re-election as a Democrat was a major coup for Senate Majority Leader Harry Reid, who is bending the Senate’s schedule to accommodate a presidential fundraiser for Specter Tuesday afternoon in Pennsylvania.

Reid announced Friday that the Senate would hold no votes after 3 p.m. Tuesday. His office later said that the scheduling decision was meant to accommodate a long-planned fundraiser that President Obama is headlining in Philadelphia to benefit Specter’s campaign.

The move could delay efforts to finish work on the fiscal 2010 transportation spending bill, which the Senate began considering Thursday.
