"Never in the history of the U.S. has a candidate faced such a deficit in the polls as Trump currently holds, with at least two well-known sites (that model the probability of the outcome) putting an 85-90 percent chance of a Clinton win," Chris Weston, chief market strategist at IG in Melbourne, wrote in a note.
