We have confirmation of the Public Policy Polling (D) survey that showed Marco Rubio doubling up Charlie Crist.

Now InsiderAdvantage (for the Florida Times-Union) shows Rubio ahead by a similar margin -- 60-26, rather than PPP's 60-28.

One poll can be an outlier. But now we are forced to believe that Crist's 50-point lead has turned into a 30-point deficit.
