40% of the turnout was over 60%.  That's the Old Timer Democrat voting block that dominated teh Party pre-Edwards, pre-Obama.  

A genunie enthusiastic Florida primary would have tuned out three million voters in the Democratic Primary.  1.6 ain't nothin compared to IA, NH, SC, NV voter participation.  Didn' even beat the GOP turnout.  Meh.

That is not the same demographic that has been voting in the contested prmaries.  FL is an abberation.
