Drier was a real fluzie on this topic til he found religion thanks to John and Ken's radio show here in Los Angeles.
I don't know about that, but Dreier has been very strong recently. He is supporting the Sensenbrenner legislation on drivers licenses for illegal aliens in the next session, and also said that Joe Lieberman's opposition to cracking down on those licenses made him unsuited for DHS Secretary when his name was being floated.
OTH Dreier in the past has expressed support for guest worker legalizations of illegal aliens. It will be interesting to see if he still does.
