Certainly having Grover Norquist testify in favor of reform yesterday didn't hurt (he's been good on this issue for years, by the way). Talking Points Memo's Benjy Sarlin has some of the best coverage of immigration on the web and his story on this subject yesterday is well worth the read. Basically, the strategy involves getting Tea Party folks on board through the help of people like Senator Marco Rubio, getting the evangelical community on board, emphasizing the enforcement triggers in the bill and emphasizing the economic arguments through folks like Mr. Norquist.
