Noah Millman strokes his chin:
John McCain, the last Republican nominee, was well-known to be a strong proponent of liberal immigration reform. George Bush similarly. Romney, on the other hand, has made a point of endorsing restrictionist positions in the primaries, and of attacking his opponents (Perry and Gingrich, most notably) for "apostasy" on this question. Romney is certainly not a restrictionist’s dream candidate – his overall pro-business orientation makes it unlikely he would propose or support immigration measures that business opposes, and he has said many times that he supports increased legal immigration. But I would argue that, based on the positions he’s taken in the primaries, he would be positioned further in the restrictionist direction than any recent nominee of either party.
