My wild guess, is that a third of Freepers quite like Rudy, a third are ambivalent, and a third think him the great Satan, or a neighborhood adjacent. Rudy would not be the nominee if the GOP voter universe were a clone of the Freeper universe.
More and more people are posting to them now, in FAVOR of Rudy.
It's just the same old, same old spammer antis.
And nobody knows how many, nor what the quiet members think...yet.
Those here who say that they will stay home, vote fringe, or vote for Hillary ( and yes there ARE some who have posted that they WILL vote for Hillary! ), if Rudy is the GOP presidential candidate are few; very few.
