Back to the title of the thread. It seems to me that Obama kos that passing amnesty is a rough ride, so he is waiting for Kennedy and Byrd to be replaced (Kennedy is sick and Byrd voted against amnesty in 2007), and waiting for Franken to steal Coleman’s seat. Still, other Dems voted no in 2007 (McCaskill was one), and Dorgan votes with the unions. And who knows? Maybe Republicans will gain some seats if Obama waits until 2011.
I think they have to make this play by the end of summer, or fail. By fall, the 2010 elections will be looming large, and trying to get Union backed, and Blue Dog Democrats, to toe the line would seem to be an impossible obstacle, even with the aide of treacherous RINOs.
