If there were any lingering doubts about how Arlen Specter would be welcomed in the Democratic Party, or if the party would welcome a primary challenge to the now-former Republican, they were put to rest during the White House Daily briefing on Tuesday afternoon.
Asked if the president would aid the Pennsylvania Republican-turned-Democrat's primary efforts, White House spokesman Robert Gibbs replied: "If the president is asked to raise money for Senator Specter, he will happily do it. If the president is asked to campaign for Senator Specter, he will be happy to do that as well."
Later in the briefing, Gibbs was pressed whether the president would consider supporting another Democrat in the Pennsylvania primary should one choose to run. He responded: "Full support means full support."
Freshman Rep. Joe Sestak, a Pennsylvania Democrat and retired Navy officer, told MSNBC on Tuesday that he was still considering a potential run at Specter's Senate seat.
Also on Tuesday afternoon, the Democratic Senatorial Campaign Committee blasted out a fundraising email headlined, "Arlen Specter Switches Parties," and declaring it "a great day for all of us who want to help bring real, lasting change to this country."
"The Democrats welcomed Sen. Arlen Specter into our party today," the message read. "This one's a game-changer. Specter's move immediately improves the prospects of President Obama's bold change agenda."
