Nothing. But shouldn’t we praise Republicans who become more conservative? Romney and Santorum have improved on immigration. Newt remains the lying backstabbing open-border type he has always been. Ron Paul used to be OK on immigration, but has veered far left in the last year.
Santorum in the last debate said that people who hire the illegals to change their babies diapers and clip their lawns should NOT have to worry about hiring illegals. So you are HIGHLY misinformed into what is St. Rick's view on illegal invasion. The gated communities and the 1% rely on illegals cheap labor.
Romney is not different on every political position that he held dear for the first 59 years of his life, he merely reversed them to run for President as a Republican.
We don't have to help him in that charade, or accept it, or condone that cynical and insulting effort.
