Assuming what you say about Christie is true, that he is conservative, he still has a major problem. He's afraid to fight against the Democrats and the media
Look at Boehner and McConnell. Both have conservative voting records. But both are failures because they don't lead and fight against the Democrats. They capitulate.
And judging by Christie's recent comments he would capitulate too.
Chris Christie has battled the media (100% in the teachers’ unions pockets) since he was elected; he simply doesn’t play their games, and points to his record (addressing voters, not the media). When he said he wanted a snowstorm for the Super Bowl next year in NJ (because that is part of the game), the media was reduced to complaining how he was insensitive to homeless people. That is what he has reduced them to; he has helped destroy their credibility here in NJ, and given them nothing to throw at him.
There is no way that that failure will allow his nomination, if any significant number of Conservatives remain in the Republican Party. Think about the implications of that signature! (It has nothing to do with toleration, precisely the opposite.)
