Newt's plummet means that one or more of Bachmann, Perry or Santorum will likely pass Gingrich, who will end up 4th or lower.
Newt in 4th in Iowa will just about end it for him, as NH won't be any more hospitable.
Plan now, to latch onto the next RomNOT. Most likely that would be Santorum. At least Santorum, unlike Newt, is an actual conservative, and without the proclivity for mistresses.
His plummet, based on a PPP_ poll really?
