Mitt Romney should refuse to answer the question of whether or not he would overturn President Obama's immigration decision. The question the Democrats and their media allies want him to answer is, "If you were going to disregard the law, is this one example of when you would?" That said, this is where a good campaign can make a difference. Romney and company need to say more about immigration. They need good surrogates to talk and write about this issue, and to shape the argument to focus on Obama's contempt for the law and where that could lead.
However, it would be best if Romney didn't have to pretend we possibly could, or that he would even be willing to, deport 12 million people. To do so is dishonest, and we pay a political price to placate a delusional few while we alienate many who want truth more than they require dogma.
The best thing that can be said about Obama's new position is that it is clever. The Romney campaign needs to disclose that it is too clever by half. Cynical pandering by skirting the law is becoming routine for Obama. But in this case, Romney is forced by the president to do something. The Hispanic vote favors Obama, and there is now a risk that Hispanics will see Romney as the enemy. Their intensity and visibility could cement fierce opposition to Romney before the campaign really starts.
