Sen. Olympia Snowe (R-ME) pledged her support for the standalone bill to repeal the military's Don't Ask Don't Tell policy this afternoon. Cloture to pass a repeal as part of the defense authorization failed by a mere 3 votes last week.
Snowe was among several theoretical supporters of repeal who said she voted against cloture because of procedural issues: Sens. Scott Brown (R-MA) and Lisa Murkowski (R-AK) objected to the time allotted to debate the underlying bill; and Sen. Joe Manchin (D-WV) said that the timing for repeal was, in his view, not quite right.
Sen. Blanche Lincoln (D-AR) said, on the other hand, that she'd missed the vote because of a dental appointment. So, with Snowe's support, repeal supporters are within 1 vote of cloture -- and a repeal of DADT.
Who knows what Joe Manchin will do. As Booman reminds us, he's not exactly on the side of actual Democrats.
