To put it in perspective, Hillary Clinton just needs to win Colorado, Pennsylvania, New Hampshire and Virginia to win the election with the way the map has fallen this year. Those states have been steadily blue in the polls for the entirety of the campaign (with the closest being Colorado).
And Clinton's ahead in Nevada and Florida (if she wins Florida it's over), it has one of the biggest Latino population in the US, and they will vote against Trump in droves. She's also ahead in red states like Arizona and North Carolina (with NC very likely to go to her), and Ohio and Iowa are looking like tossups (Clinton doesn't even need those two)
Even if Trump wins all of Ohio, Florida, Nevada, Colorado, North Carolina, Iowa and Arizona just to get to 274. Clinton just needs to win one of those and it's lights out, Trump is pushing shit uphill and have been for a long time
Enthusiasm for Clinton is not great but she has inherited Obama's ground game operations which is probably the best in modern democratic history in the way it drove turnout, whereas Trump has not even bothered to set up proper ground game in vital states like Florida (where the head campaign runner in Florida kept bugging him for that 1.5 mil to set up offices just 6 weeks before election day, but it never came and he got sacked afterwards). There are huge differences in how both campaigns have run its operations professionally and I think it'll tell come Nov 8th
