In case you have nothing else to do, I’ll be participating in a one-hour online Q&A on immigration from 2 to 3 p.m. EDT (i.e., right now) at this (liberal) site. The other participants will be the guy who wrote the recent study estimating that it would costs zillions of dollars to enforce the immigration law, plus a woman from the National Council of La Raza (two against one is good odds for me!).
