MICKEY KAUS: Jeb Bush’s Cunning Strategy. “He’s not running, but he’s making space for Marco Rubio. Look at it this way: The GOP establishment is desperate to suppress Tea Party conservatives and also obtain the immigration amnesty they believe will win Latinos and relieve them of the need to do too much rethinking in other areas. P.S.: The need to rehabilitate Rubio–-which means avoiding a big immigration fight, at least in 2015 and 2016–-would be one more reason the GOP establishment might feel it’s now-or-never for passing an immigration reform bill. That would help explain the increasingly desperate and sneaky (but possible successful) efforts to keep amnesty alive.”

Meanwhile, a different perspective here. But Kaus’s theory seems more likely, though what do I know?

UPDATE: More: “The problem is, Jeb Bush is another moderate like McCain and Romney, both of whom failed to deliver. There is no reason to think he’ll do any better.”
