Sen. Ted Cruz has already convinced us many times over that he’s not going to be cowed by all of the usual Beltway tactics. Accusations of being the reincarnation of Joe McCarthy? Cruz swatted that one away with a clip from “Casablanca.” A Latino in name only? Cruz didn’t even have time to react to that tweet before it disappeared. He’s already embraced the “wacko bird” nickname given to him by Sen. John McCain, so don’t think that Sen. Bob Menendez (D-N.J.) attributing Cruz’s opposition to the Gang of Eight’s shamnesty bill to “Obamaphobia” on MSNBC is going to result in any policy flips on immigration reform.
