Romney wouldn't take New Hampshire, and Christie would probably be so elitist that Missouri would actually swing to Obama,maybe North Carolina too.
New Jersey to Romney...perhaps,but I doubt it.
If by elitist you mean rich/think of themselves as important, Romney was that too - and he won Missouri by about 10 points - the reason it took a while to call on election night was because 1) it counts as slow as a snail, and 2) the networks, for one reason or another, don't have a lot of trust in Missouri's exit polls. It'd be (non-atlas) red with Romney/Christie, by probably about the same margin.
