Senator Olympia Snowe of Maine is the latest Senate Republican to voice support for ending “Don't Ask, Don't Tell.”

After House members on Wednesday overwhelmingly voted in favor of ending the law that bans gay and bisexual troops from serving openly, Snowe announced she was prepared to do the same.

“After careful analysis of the comprehensive report compiled by the Department of Defense and thorough consideration of the testimony provided by the Secretary of Defense, the Chairman of the Joint Chiefs of Staff and the service chiefs, I support repeal of the 'Don't Ask, Don't Tell' law,” Snowe said in a statement.

The Senate is expected next week to take up the standalone version of repeal introduced after the chamber twice failed to approve repeal language bundled within the annual defense bill.

Three additional Republicans – Susan Collins of Maine, Lisa Murkowski of Alaska and Scott Brown of Massachusetts – have said they conditionally support repeal. Only Collins crossed the aisle last week to join all but one Democrat, West Virginia Senator Joe Manchin, in voting for repeal.

However, the new standalone version removes most of the procedural objections cited by Republicans.

Snowe's announcement suggests repeal advocates have the 60 votes needed to repeal the law.

Advocates also believe two additional Republicans – George Voinovich of Ohio and Richard Lugar of Indiana – are leaning towards repeal.
