It's disappointing (and in some cases very surprising) to see some on the right turn their backs on the vision of Ronald Reagan on immigration, as today's Wall Street Journal editorial argues, and seek to purge the GOP of dissenters. "The GOP is losing this one for the Gipper," the editors note, as the "GOP's nativist wing" seeks to "hijack the Gipper's reputation" to push their cause. Look out Gov. Jeb Bush. You could also be part of the purge given your apostasy on immigration. If things keep going the way they are, the Grand Old Party should consider renaming itself the "Over-the-Cliff Party." Disappointing and depressing, indeed.
