FR is here to stay in spite of all the Romney trolls that show up... Flip Floppers do not last and neither do Rinos. They tend to slither over to the DEM party where they belong.
An awful lot of FReepers who relentlessly trashed Newt supporters last summer (As an early Newt supporter, I was on the receiving end of that) became newly-minted lifelong Newtistas about thirty seconds after FR officially became "GINGRICH COUNTRY!!"
So flip-flopping is actually a survival skill here...........
