The reason Newt has catapulted to front-runner status is the same reason Bachman, Perry, and Cain were catapulted to front-runner status.
1) The corporate media decided they wanted the candidate to be a front runner.
2) The media told everyone we should keep an eye out for that candidate surging.
3) The media followed and showed everything possible about the candidate, capitalizing upon and screaming about every victory, small or big.
This is precisely why you've seen FOUR candidates now shoot rapidly to the top. It is also the same reason why the previous three fell to the wayside after their month in the spotlight, and the same reason why Newt will be history in a month.
The media is throwing every candidate they can after Ron Paul, one at a time, to see if any of them will stick. Who knows, maybe Newt somehow will, but I find that hard to believe with his insane ethics problems, infidelity, insider position, corruption, and taking bribes from Fannie/Freddie.
In the end, the race will be between Romney, whose support has been unenthusiastic and waning over the course of the campaign, and Ron Paul, whose support has steadily increased despite continual lack of media coverage, and outright media blackout.
