Is Sen. Brown (D-OH) on the fence? Brown, a purported ally of labor, voted in favor of cloture last time, but I am hearing (thanks to some readers) that he has concerns and "serious reservations" about elements of the bill, especially the "guest worker" program and that he is undecided about cloture next time. So could he switch to vote against cloture? Especially now that the AFL-CIO is against the bill?
