Lawmakers just finished bloodying each other over the revamped farm bill.

But longtime schoolteacher Rep. Mark Takano, D-Calif., is already looking forward to the next battle, breaking out his trusty red pen to mark up and grade a “Dear Colleague” letter from House Republicans warning Speaker John A. Boehner to tread carefully on any immigration overhaul.

Per Team Takano, Republicans have yet to weigh on the California Democrat’s biting critique.
