Why is OP continuing to make so many generalizations about Hillary's entire campaign from literally one ad he saw
Why are there so many deplorable and bad posters with terrible opinions
The inane "the Democrats should ignore how awful Trump is and instead attack him on his tax policy!" or whatever concern trolling line has been around all election season. It's because the people spouting it get upset when the existence of racism/sexism is acknowledged.
It's fairly simple. About 40% of Americans are deplorables who'd vote for literal Hitler if he had an (R) next to his name (or, actually, would probably do so more enthusiastically than for a generic Republican). Add a couple of points on to that for idiots and lunatics and you end up with the roughly 42%-43% Trump is consistently getting and will get on Election Day.
Jesus F. Christ, what is it with all these trash polls lately??
Discredited fraud Nate Silver basically ruined the polling industry by popularising the miracle of aggregation and averaging, meaning that ARG and random junk uni polls are all we're getting, apparently.
