If those states stay the same colour (blue for Clinton, red for Trump) through to election day - and both candidates win the remaining states they are expected to - it would be a clear victory for Hillary Clinton.
For Donald Trump to have a chance, he needs to turn Florida and Ohio red and win a few others too. As it stands, Clinton is ahead by a pretty small margin in both Florida and Ohio.
