Of course, given earlier threats by Jim DeMint (R-SC) to demand full reading of other bills on the Senate floor, it's still not clear that the DADT repeal bill will get a chance to be voted on. The Party of Hell No could well be looking to run out the clock, and Brown and Murkowski might know that, and might just be trying to buy themselves some cred as "reasonable," knowing that they won't actually have to cast the vote they've said they will.
Cynical about Republicans? Moi?
I look forward to being proven wrong.
