These straw polls are exactly for that purpose. All primary polls in general, are very unreliable. No one saw janet Reno losing the nomination in 02. Her ideological twin Charlie Crist may well lose in similar fashion. Rank and file Republicans, the kind that actually vote, are fed up with Crist, especially after last night.
(Crist's loose lips sink ships.)
He sticks his foot in his mouth quite often. I'm hoping he'll do it again at the next televised debate.
