Very good question. On the first point about Trump 'walking' the election Implied probabilities of a Clinton victory are c. 85% at betting exchanges. I believe this figure to be woefully inaccurate and here is why. Firstly the polls are not picking up 2 groups of people. i) shy trumpers ii) people who have never voted before. A substantial % of people will not openly admit to voting trump in public or more so social circles. The second group do not respond to polls, they either hang up the phone or don't do online terribly well. The majority of the polls are run by companies owned or controlled by the establishment hence over sampling is rife. Something like the Rasmussen poll is more independent and this shows them virtually neck and neck with momentum in Trumps favour. Once you add in the 2 groups above I believe Trump will win comfortably, c 55% 45%.
