Apparently this is no longer operative:

Senate Majority Leader Harry Reid (D-Nev.) said Friday that Sen. Arlen Specter’s (R-Pa.) decision to reject “card-check” legislation has ended any chance of a party switch.

Reid as well as Vice President Biden, Pennsylvania Gov. Ed Rendell (D) and Sen. Bob Casey Jr. (D-Pa.) have tried recently to persuade Specter to leave the GOP.
…

But Specter smashed those hopes by declaring this week that he would vote against any effort to quash a filibuster of the Employee Free Choice Act, also known as the card-check bill.

“Yes, I’ve talked to him,” Reid told reporters Friday of his efforts to convince Specter to leave the Republican Party.

“But he, in coming out against card-check, stopped everyone from being able to help him.”

Per usual, I would love to get a seat at Harry Reid’s poker game.
