Another Republican Vote For DADT Repeal

Collins is onboard. That makes 60 votes, enough to override a filibuster, provided all of the Democrats can be kept in line. But Collin's vote comes with a big caveat, as Allahpundit notes:

Collins, at least, is sticking by the GOP’s plan to vote no on everything until a deal is reached on the Bush tax cuts. Brown’s statement doesn’t address the subject, but since he also signed the Republican pledge to make the tax cuts top priority, presumably he’s on the same page. Until something happens on taxes, this is all meaningless. Which brings us to the second qualifier: Will there be any time left in the lame duck to address DADT even after a deal on taxes is reached?
