What do Republicans do if the nominee is someone like McCain or Huckabee, who can’t wait to welcome more immigrants and offer amnesty to the illegals already here? (And after his record as governor, I can’t just blithely accept Huckabee’s sudden switch—ie, signing a “pledge”. A record of years of proactively welcoming illegal immigrants, and giving priority to legal immigrants over citizens, as in tuition fees, doesn’t just go away with the stroke of a pen).
It will be too late to do anything constructive, at that point.
The only reasonable thing to do, in my view, is to get behind Romney. He is a sure bet to win in November, if Republicans are smart enough to nominate him now.
