As for whose voting. The polling since the first debate has been going against Trump. Clinton is further ahead this week than she was last week. No candidate has been as far ahead as her and lost the election.

For Trump to win then:

1) Something needs to happen that changes the dynamics of the race so far. Focusing everything onto Clinton.
2) Any 'hidden Trump' vote will have to be massive. All the pundits are searching of this as it's the biggest theory going as to why Trump might still win but it's hard to see where that hidden vote is.
3) Massively depressed turnout amongst women and minorities.

Probably a combination of all three.
