Yes, of course. This is tautological. Do Trump's supporters, who are largely working class, represent the working class...yes.
Several states that haven't voted Republican in 30 years voted for him en-masse because of their lack of representation elsewhere. If you're asking if Trump will represent the working class in the future, then my answer is that I don't know, but in his short time he's done what he promised.
If you think that states switched from Democrat to Republican because of trolls then, I'd also suggest that you're out of touch with certain demographics.
