Maybe not only did the Kremlin want "pay-back", maybe millions of "deplorable" voters in the U.S. also wanted pay-back? By Hillary Clinton's calling voters bad names, that probably gave those voters more motivation to actually show-up at the polls. Meanwhile there were Black American commentators who told their audiences: "We are being used by the Democrats".  That message probably kept a lot of voters at home when in previous elections, they came out and voted for Obama.

South Park's parody of Hillary Clinton's debating style, while being extremely exaggerated,  might also have also triggered the notion in voter's minds that there was, in fact, a germ of uncomfortable truth in that parody.
