Defeating the next amnesty push will require several Dims. I know Tester has voted against it, and Byrd. Do you recall other Dims who opposed amnesty in 2006 or 2007? What did Landrieu and the Arkansas Dims do?
The Senate vote was 62-36 for passage. "The usual suspects," for the most part, adding in Bennett, Brownback, Gregg (a NWO dude), Lugar, and McConnell. Landrieu was in the AYE column too. The only DEMs against were Byrd, Dorgan, Nelson of Nebraska, and Stabenow.
Some sort of immigration amnesty is inevitable. Congress (actually, the government as a whole, but in this case it'll be Congress) is expert at making profound errors, then compounding them.
