Clinton carried the white working class electorate at 53%, and while that's ten percent down from Obama's sweep amongst blue collar whites in 2012, it's still a much different picture from this super idiotic characterisation of pro-Trump momentum being spearheaded by some white proletariat groundswell.
Seriously speaking, half of Hillary's and the Democratic Party's and, really, the American "left's" (such as it is, anyway) problem in general is the complete refusal to incorporate class analysis and address the needs of the poor such that there is a viable alternative to reactionary nationalism. I mean, you wanna talk about gendered wage loss or whatever, but that is no answer for women in poverty, nor is it acknowledge the difficulty of securing employment in the first place.
I also find it interesting that there's a tendency, across borders, even, to try to pin the rise of fascist sentiment to just differences in class and education as if the working class is entirely just white (which is especially untrue in the States). But I guess [Mariame Kaba voice] that's normal.
