BYRON YORK: Jeb Bush immigration flip could upend amnesty debate.

Bush, who would be a leading contender for the 2016 GOP presidential nomination if he chooses to run, is generally regarded within the GOP as liberalizing voice on the issue of immigration. A longtime supporter of comprehensive immigration reform, Bush has in the past supported a path to citizenship for the 11 million immigrants currently in the country illegally.

But now, in a new book, Immigration Wars, Bush proposes a plan under which those 11 million — or at least the ones who came to the United States illegally as adults — could gain legal status but would never be eligible for American citizenship. The only way for them to find a path to citizenship would be to leave the United States, return to their native country and wait for a chance to come to the U.S. legally.

Hmm.
