I'm not certain that the House won't pass it. I wish I remembered the link, but I remember reading about a month ago that Sensenbrenner will be outnumbered 3 or 4 to one during the reconciliation phase. And House Republicans are probably being informed that any campaign fund-raising with White House personnel is contingent on voting in support of the bill.
The White House will pull out all the stops to pressure the House into agreeing to a bill acceptable to the Senate and Bush. We will never know all of what goes on, but it will be like making sausage.
I may be worng but I don't think the House will cave. We'll see.
Two can play at that game. All the House has to do is remind the WH that should the democrats get power the next two years aren't going to be very much fun for them.
I would not count on the House defeating this amnesty bill. Remember how we were counting on the SCOTUS to overturn McCain's campaign finance bill? The media will be all over the repubs in the House and I would bet even money that they cave.
