Good point.
Romney then used ingeniously ambiguous language that lends itself to multiple interpretations, including the idea that he just might be open to finding a way for illegal immigrants to stay in the United States:This will be a priority of mine, if I become president, to make sure we finally reform our immigration laws step by step, secure the border, improve our legal immigration system, so we can keep people here and welcome people here who will make America a stronger nation.
Notice that so we can keep people here. For those interested in the subtle movement of politicians away from the ideological extremes they advocate while primaries are underway, the most interesting part of the Romney transition is almost certain to start very soon.
This is the same Romney who was oh so truely anti-illegal when Rick Perry or Newt Gingrich were getting heat.
