Writing at Slate, Reihan Salam describes how Marco Rubio has dodged the illegal immigration issue. It is an issue on which his former pro-amnesty positions put him at odds with most GOP voters.
Illegal immigration is also the issue on which Ted Cruz has been most able to distinguish himself from Rubio; Cruz has taken an uncompromising stance against illegal immigration. A far-from-wealthy candidate, it is unclear whether Rubio can afford to cross the party's big money backers who love all immigrants as cheap labor and avid customers.
Unfortunately, the only reason the MSM will try to pin Rubio down on the issue is because he might be the GOP's most formidable opponent to Hillary Clinton. Whatever, as long as they have a motive, it will suffice. Rubio's position on this key issue must be made clear.
