Look at the numbers
http://www.electoral-vote.com/
289 delegates Clinton
245 delegates Trump
4 delegates tie
Florida has 29 delegates which they are counting in Clinton's column. She has a 3% lead there by their reckoning.
If Florida voted for Trump the delegate count would then be:
260 Clinton
274 Trump
4 tie
270 delegates are needed to win.
If you want to throw electoral-vote.com's numbers out the window without so much as a thought... upon what grounds would you do so?
