Sen. Specter has delayed Judiciary Committee action on immigration from February 9 to March 2. Probably this is partly because of hearings he’s planning on the NSA eavesdropping program, but it may well be because the path to a guestworker amnesty got a whole lot rockier this week, and he wants to shore up support. This is because Jim Sensenbrenner, who will be the chief House negotiator trying to reconcile last month’s House bill (H.R. 4437) whatever the Senate passes, came out this week as categorically opposed to any legalization program. In his words: “A guest-worker program that applies to illegal aliens already here is an amnesty.” I don’t see any wiggle room there.
