Barack Obama visited El Paso, Texas today to jump start the case for comprehensive immigration reform, yet again, as well as to make fun of Republicans. He mocks the party's ever-moving goalposts on border security, such as wanting more and more troops on the border and demanding an even "higher" fence. "Maybe they'll need a moat," he went on. "Maybe they'll want alligators in the moat." You mean we haven't even tried this yet? Well, now it's too late; alligator prices are through the roof these days.
