How does “Perry do it too?”
Pretending to conservatives to be for "border control" and "against illegal immigration" not long after pandering to a bunch of racists at a La Raza convention is a fine example. "Border control" and "anti-illegal" are both subject to interpretation. One can "control" a border by letting everybody through, as control only means that it is being used as intended. One can "oppose illegal immigration" by allowing the same people to become legal residents.
See? It just had to be easy, as even Rick Perry can do it.
