On a party-line vote, by my count. All
41 40 Republicans voted against the majority’s effort to staple a Don’t Ask / Don’t Tell repeal onto a defense appropriations bill.
UPDATE: New vote count, 56-43. Lisa Murkowski (R., Alaska) missed the vote. Roll-call here.
Democratic Senatpors Pryor and Lincoln of Arkansas both joined the Republicans, as did Senator Reid (for procedural reasons).
