Sen. Mark Pryor’s office has told an Arkansas blogger that the senator will support the Employment Non-Discrimination Act when it comes up for a vote in the Senate, possibly as soon as next week.

Max Brantley of the Arkansas Times reported Tuesday evening that a staffer for the Arkansas Democrat confirmed that Pryor would vote “yes” on ENDA. The bill would bar employment discrimination because of sexual orientation.

If the report is true, the only Senate Democrat who has not signaled support for the measure is West Virginian Joe Manchin III. Sen. Bill Nelson, D-Fla., signed on as a co-sponsor of the bill earlier Tuesday. Fifty-three members of the Democratic caucus and four Republicans have now signaled their support for the measure.

The measure will likely still have to overcome an attempted filibuster. Senate Democratic leaders have not yet nailed down the 60 votes needed to beat back such a blockade, but Pryor certainly gets them closer to that goal. The swearing-in Thursday of newly elected New Jersey Democrat Cory Booker is also likely to help with the count.
