From Public Policy Polling, which typically surveys for Democrats and liberals. Note: It looks like it didn't poll a Charlie Crist-Alex Sink Democratic match-up:
Raleigh, N.C. – While Floridians might not be familiar with some of the potential Democratic candidates running against Governor Rick Scott for the Governor race in 2014, poll numbers show that they are not happy with Scott’s job performance.
Florida voter approval of Rick Scott’s job performance is 33% with 57% disapproving.
When asked about the favorability of newly turned Democrat Charlie Crist, the former Republican Governor of Florida, voters have a 49% favorable opinion while 38% have an unfavorable opinion of him.
Among Republican primary voters, Governor Rick Scott has a 56% approval rating and 32% disapproval rating. When pitted against Republican Pam Bondi for Governor in 2014, Rick Scott leads (49-25). If challenging Republican Allen West, Rick Scott trails (37-38).
Pitting the former Governor against the current Governor, Floridians said they would vote for Charlie Crist over Rick Scott (53-39). Other possible Democrats running for the Governorship are either not as well known as Crist or not as favorable.
“Rick Scott continues to be one of the most unpopular Governors in the country and most Democrats are embracing Charlie Crist now that he’s officially joined the party,” said Dean Debnam, President of Public Policy Polling. “It’s early but Crist looks like the favorite if he tries to get his old office back next year.”
