Those Georgians! Brothers in arms!: From the AJC's Political Insider (again), a prediction about how Sen.'s Chambliss and Isakson will vote:

We’re betting that both Isakson and Chambliss — despite their strong roles in the negotiations — will vote against the bill, and that it will still pass.

Whatever the two senators do, they’ll do together. This particular strategy may be the salvation of Chambliss, who’s up for re-election next year.

By linking themselves arm-in-arm on this issue, they’ve sent a message to the most militant opponents of the immigration deal: To attack one, you must attack both.

But will they vote for cloture? They're still toss ups, it seems to me....
