Although people often talk about how "this thing could be over by NH", Only a fraction of delegates are being decided in all the contests before Super Tuesday.
I think that January and February will winnow the field down to Romney, Paul and one conservative (probably Perry or Gingrich). And even if that conservative hasn't won any races until that point, they will still ahve a chance because there are still 80-90% of the delegates still up for grabs
Sorry, but, neither Perry nor Gingrich are conservatives.
