Sam Brownback voted “AYE” on bringing the immigration deal back to the floor. I suppose he could still vote “No” on the next cloture (which cuts off debate and brings up the bill for final passage), but nonetheless, this is probably going to lead to some hostile questions on the campaign trail…

Final vote was 64 to 35.

Yes, a bill that’s polling at 22 percent approval and 50 percent opposition got 64 Senators to say, “let’s bring it back to the floor!”

There’s still a possibility that four or five of today’s yes votes decide not to cut off debate. But I wouldn’t bet a lot either way…

UPDATE: Team Brownback specifies, “Senator Brownback voted in favor of cloture on the motion to proceed to the immigration bill today. That means he voted to bring the bill back to the floor for debate and for amendments to be offered. This does NOT mean that Senator Brownback supports the immigration bill itself – he feels the bill needs to be improved. “

Brownback lays out his thinking here.
