Having worked for a polling company, I can tell you that these numbers are essentially meaningless.
First of all, It was a telephone poll of only 600 people. That's a very small sample size.
Secondly, you must ask if the 600 people are proportionally representative of the Florida population's demographic profile.
Think about it: who answers these telephone polls? Opinionated people with time on their hands. In Florida, that means welderly (wealthy seniors).
Florida is a battleground state - no question, but a poll of only 600 people cannot be accurately projected to the greater population.
and who are the people most likely to vote . . . opionated people with time on their hands (coincidentally enough - wealthy seniors.)
