As I already noted before, the US eelction is not a popular vote election, but an electoral vote election.
As electoral votes as of 3 October we have Clinton 201 vs Trump 165 (difference 36) – in balance are 172 votes
The win is 270 electoral votes.
So Clinton has an advantage, but Trump cannot be discounted.
For example in August Clinton had 288 votes and Trump 174 (difference 114) and in July was 255-190 (difference 65).
So, looking forward to next Monday debate!
