Unsurprising. Clinton was a plutocratic candidate, and her campaign did an exceptionally poor job of representing working class interests. What little her campaign offered to working class people (minimum wage, TPP, etc) was belated, inadequate and unconvincing.
Despite that, they were still the only group in which the majority opposed Trump’s bigotry. The attempt by the media to blame the working poor for Trump is seriously pissing me off.
