My friend and former Bush-Cheney White House colleague Peter Wehner is spot on with his take on the GOP’s fascination with ending birthright citizenship for the children of illegal immigrants. According to Wehner, Republicans “are manufacturing an argument to create an issue” and this “is not what the party of Lincoln should stand for.” Amen, brother.

When asked about changing the Constitution to bar children of illegal immigrants from becoming U.S. citizens, House Minority Leader John Boehner said, “I think it’s worth considering.”

No it’s not.

I’ve previously laid out my reasons why this is a very bad idea. It’s worth adding that children must turn 21 before they can sponsor their parents for legal residency. It is simply not the magnet that people like Boehner and Sens. Lindsey Graham, John McCain, Jeff Sessions, and Jon Kyl insist. They are manufacturing an argument to create an issue.

There is plenty policymakers can do to curb illegal immigration (including securing the southern border, toughening enforcement policies, and expediting the legal process to cut the average deportation time) and improve our overall approach to immigration (including narrowing the scope of the family-reunification privilege to the nuclear family, adjusting upward our quotas for high-skilled labor, and making assimilation a central national priority). Pushing for altering the 14th amendment, though, is worse than unhelpful; it is substantively unwise and politically harmful.

Republicans are practicing the politics of symbolism in the worst way possible. They are embracing a policy that doesn’t have any realistic chance of becoming law, that will be unnecessarily divisive and inflammatory, and that, in the long term, will be politically counterproductive.

It is an approach that is, among other things, wholly at odds with the one embraced by the last two Republican presidents to win reelection, George W. Bush and Ronald Reagan (see here).

Why Republicans continue to travel down this road is a mystery to me. This is not what the party of Lincoln should stand for.
