"Honestly Hugh, I don't understand this push by conservatives for immigration reform."
The main thing to understand is that those pushing immigration reform are NOT Conservatives. The Conservative view on immigration is
1. The goal of "Immigration Reform" is amnesty-period
2. The problem with immigration is due completely and totally to an unwillingness to enforce the law. Arguments that say with "We can't deport" means the speaker doesn't want to in the first place
3. Until immigration law is enforced all the rest is an exercise in fraud or stupidity or both.
