if romney wins SC....

Is it over then? I imagine a few poor souls will stay in until Florida, but honestly, does anyone other than Paul stay in long than that?

I think this could be finished REAL fast.

Depends on how decisive the victory is. If it's another "victory" like the one in Iowa, things will certainly not be decided.

[Joe Biden 2020]

Like Dessie said, it all depends on the margin of victory.  A blowout and it's over.  A Iowa-like victory and we can probably expect things to last through March 6 Super Tuesday.  Even if Romney wins Florida, it's not going to mean a whole lot, IMO, because he should be expected to win there with the New England transplants.  Nevada is largely Mormon, as well, so that's not going to be a big factor.  Then, with relatively few states in February and a full 3 week break after Nevada, we're going to be headed into March 6 with at least Romney, Paul, and Santorum.

If the results are anything like the CNN poll, then yes. The worst is waiting till Florida for the knockout blow, by which time everyone but Paul drops out and Romney's the presumptive nominee.
