Greg Sargent explores the immigration debate on the right, and explains why Marco Rubio and others are making the arguments they’re making:

They are subtly making the case to their base that a defeat for immigration reform is actually a hidden victory for Obama….The idea is that if we don’t pass the Gang of Eight plan, Obama wins. This case is being made on several levels. On the one hand, this notion of leaving the issue “entirely in the hands of Obama” is a partly a suggestion that the President just may use his executive powers to solve the undocumented immigrant problem himself if we don’t pass the Senate plan — just as he did with the DREAMers.

….There’s a key nuance here. As I understand the thinking, GOP base voters are turned off by the political argument that we must reform immigration because if we don’t, Obama will be able to screw Republicans over politically with Latinos….That’s why the argument can’t be openly stated as: If we embrace reform, Obama loses. It has to be carefully calibrated in the manner Rubio has adopted: Not doing anything opens the door for a far greater victory for Obama later. He will be able to do for the undocumented what he did for the DREAMers — while not securing the border — a twofer for Obama.

Obama is playing his part in this dance, too. He and the White House frequently take care to say — not in these exact words, but this is the message — that while he supports the Senate compromise, it’s far from the liberal dream legislation he’d like.
