Here's a good look at why Ohio and Florida are important as far as keeping Trump out of the White House

I thought the really important GPfact about Trump (after the GPfact that his conservertarian-fu is weak) was that we will lose the election if he heads the ticket.
So why do we need to worry about keeping him out of the whitehouse ?
