Maybe Rich Lowry is right to shine a light on Rubio’s immigration policy. It makes sense to force the Florida Senator to be clear on what he promises as far as immigration goes. Maybe Rubio will win the GOP nomination. Maybe Jeb Bush will win. Maybe Rich Lowry will be President Bush’s Press Secretary. Maybe he will instead have to decide on what kind of editorial to write in the National Review when Trump wins the nomination.

The future is uncertain to say the least, and immigration needs to be defined as an issue with doable policy proposals. It seems the absolute size of the illegal immigrant population in America dictates a we-can’t-do-that attitude on the part of many analysts and politicians. So what could be done in terms of border security, and more to the point, border enforcement?

While E-verify, entry & exit tracking systems, and prosecution of illegals upon entering the country are concrete steps, they need to be seen as coming from a united front. Not just from the White House and Congress, but from business as well. And that means filtering legal immigration through a points-based skills test that means America gets workers it needs.

Does America need immigrant workers? Toll Brothers says yes indeed. Fast food franchises, hotels, casinos and other recreational industries say yes. Tech says yes because they’re cheaper and we can fire Americans and pay less. If the answer to this question is to be based on evidence, then a light needs to be shined on hiring practices. That’s fairly simple to do and has been suggested repeatedly: significant penalties for hiring illegals, and strict standards for H1-B visa holders.

Will Marco Rubio agree to all that and be judged on his words of promise? The question is: how much does illegal immigration really bother many in the GOP? If it doesn’t, then Rubio can basically promise what he thinks is expedient and get away with it.
