It seems like early voting in crucial states is strongly leaning towards Hillary, with record turnouts for Hispanics, women and minorities. FL and NC might go blue, NV will most definitely be blue. Trump has only white males (and less minorities and women than Romney) voting for him and they don't outnumber the rest of the nation. Trump doesn't have a path to victory with these numbers.
Also there's rumors that inside the Trump campaign the new goal is not to win the presidency anymore, but to get more electoral votes than Romney to prove to the GOP base that Trump was the right decision.
Yes, there is much more enthusiasm for Trump, thousands of yard signs, huge rallies, tremendous support. But in the end none of this matters. What matters are votes and so far Democrats are doing a much better job. Hillary united enough people against Trump to win the presidency, it's as simple as that.
It's only three more days, there's no time left to gain more voters and there won't be another big new leak or scandal or whatever. This is it.
Not CTR btw, I'd love to be proven wrong.
