What does he mean by “constructive immigration reform” if he means amnesty, no thanks. If he means an actual immigration reform process (e.g. strengthening our borders but making it easier for LEGAL immigrants to come here) then maybe it is worthwhile.
"Immigration reform" is as always a euphemism for amnesty. It's like calling a tax hike a "revenue adjustment." The use of the term "reform" is designed to distract attention from the fact that the system we have isn't really in need of reform, it's in need of enforcement. So we have these political charlatans telling us that we need "reform" because it saves them the trouble of doing something about enforcing the legitimate laws that are already on the books.
As for simplifying legal immigration, I guess that depends on who we let in. If we simply open the gates to all of the riffraff from Mexico and the rest of the Third World, no thanks. If it means simplifying the red tape to allow a small and select number of people with skills, education, and the potential to assimilate into US society, by all means.
