With the political media’s attention trained on scandalmania, coverage of the immigration reform push has gotten short shrift in many quarters. In recent days, we’ve seen signs of trouble in paradise, with Marco Rubio huddling with skeptical House conservatives, and Democrats fretting that they don’t have the votes to pass the ‘Gang of Eight’ package through the Senate. Rubio, the GOP point man on this issue, has also begun chirping about abandoning his own “gang’s” proposal absent significant border security upgrades. Enter Sen. John Cornyn, a Texas conservative, who plans to roll out a significantly beefed-up security package as an amendment to the Senate bill. Guess who basically co-authored it?
