Having the perfect position is of no value if you cannot get it enacted or enforced. And in that circumstance, I would not let the perfect be the enemy of the good. I'll take something that secures the border and eliminated 75% of the illegals already over here over the status quo in a heartbeat.
Gingrich is part of an elite establishment with a proven dedication to mass immigration, despite the great harm inflicted upon average Americans. Unless Gingrich really defects from the establishment, he will continue to at least implicitly support mass immigration like the past several presidents up until now. Any Republican candidate that again ignores the popular will on immigration will likely lose to Obama.
