Vice President Joe Biden Tuesday morning would not say if President Barack Obama would hit the trail for Sen. Arlen Specter (D-Pa.), but the president isn't completely absent from the campaign.
Specter came out with a new campaign ad Tuesday that features a past Obama campaign speech on his behalf.
The Republican-turned-Democrat faces a tough primary challenge from Rep. Joe Sestak (D-Pa.), who has taken a lead in some polls. Voters head to the booths next week to select a Democratic nominee.
The president has endorsed Specter, who helped Democrats gain a 60-vote super-majority in the Senate for a time. Sen. John Kerry (D-Mass.), the previous presidential nominee for the Democrats, was the latest high-profile Democrat to back his Pennsylvania colleague Monday.
Obama has made big campaign stops for losing Democratic candidates before, such as Massachusetts Attorney General Martha Coakley, who lost to Sen. Scott Brown (R-Mass.) and former New Jersey Gov. Jon Corzine, who Chris Christie (R) booted from office last year.
