Hillary openly used racial rhetoric, addressing "white privilege" and how we need to recognize it. Bernie didn't employ identity politics during his run which is why I liked him, but he has since embraced them unfortunately.
I don't get where you're coming from that the gop are based on racial resentment. Certainly in the past that has been true, like decades ago, but much of that has faded with a lingering spirit still remaining. I don't see the gop and right leaning news openly hostile to and condemning entire swathes of society based on their skin color or gender. However on the left we get to hear from npr, bbc, msnbc, the hill, vox, buzzfeed and MTV about how evil white people are. How all whites are racist. How racism towards whites is impossible. How all men are sexual predators. Etc etc
