Every losing side always thinks this. The difference is that either you correct it with something effective or you just bitch about it
I can tell you that this particular white liberal is thinking nothing of the sort. I'm thinking that they are a voting bloc - one of many - who are hoping (in vain, as it will turn out, whoever wins) for a return to a pre-Trump landscape. That's why the electability argument for the Sanders campaign has been almost impossible to make to these demographics. They needed to attack the past few decades of American politics and argue that Trump was the logical outcome of the system rather than an absurd break from it, so don't vote for the former Obama guy. Unfortunately, it turns out the Democratic base seem to want nothing more than an Obama 2.0 (which would be fine if Biden were actually Obama 2.0 and not a half-senile Establishment shill who can barely make it through a sentence anymore). Sanders' only hope was trying to bypass those voters with youth turnout, and when that failed the campaign was finished. It has nothing to do with black people being stupid and everything to do with America preferring to stay firmly on its downward trajectory rather than entertain the notion that maybe, just maybe, its brand of capitalism - and the war-mongering imperialism that sustains it - is dying.

Typical, you completely back down the moment anyone comes in with a substantial post. You coward.

Racism is not "a substantial post"
@previous (A)
Oh that's bad news. I regret to inform you that none of your posts are substantial then.
