No, because many of the Democrat candidates running against Republican candidates also opposed illegal immigration and amnesty, such as McCaskill in Missouri and the democrat who beat J.D. in his Arizona congressional race. I don't think the Democrats want to risk losing control of Congress by passing an Amnesty bill which would rock the boat for the elections in two years.
No, they will just betray what they said during their campaigns with some phony call for bipartisanship to provide cover. I will be shocked if amnesty isn't a done deal before the 2008 elections. Oh they might call it something else, but it will be amnesty.
