From Zero Hedge:
Per Politico, in 2008 and 2012, Obama received 95% of the 1.7mm votes cast by black voters in Florida. Unfortunately for Hillary, a recent poll from Florida Atlantic University found thatshe is only polling at 68% among black voters while Trump is polling at 20%. Now, if you assume that black voter turnout drops just 5% in 2016 and that Hillary’s support drops from 95% to 70% that could cost her over 500,000 votes in a state that Obama only won by roughly 75,000. When factoring in the higher support for Trump this could swing the overall Florida race by 7 points…not a good sign when Obama narrowly won the state by less than 1%.
