You're in serious denial if you think Bush, Kasich or Christie will perform better than Trump in New Hampshire.
Nope. I have very good reasons to think so. I see that Trump must be some kind of God to you, since you hide away from all obvious historical and other facts so evidently there to see that one would simply have to be blind to not even recognize them being there. 
Trump is definitely a better campaigner than Santorum in 2012, yet he's still a far worse messenger than Huckabee was in 2008. And where did Huckabee end up? Right. If Huckabee couldn't challenge a seriously wounded McCain in 2008, then how on earth could Trump come anywhere near to Rubio, who is one of the best campaigners the Republican party has ever seen since it's inception (unlike McCain who was quite mediocre to say it very mildly).
Trump is a vastly superior candidate to Huckabee, and everything that's occurred thus far suggests he won't be taken down so easily. He's basically reinvented the way campaigns work this cycle, and everyone else is busy playing catch up.
