Nothing new about divide and conquer, it is what it is.
Divide the electorate into racial and socioeconomic sectors, demonize the ones that vote Republican, tarnish as many people as possible with the unacceptable label of racist or sexist, instruct their loyal voters to repeat it endlessly why someone is unqualified so they don't listen to anything else they say, then becry the country being divided.
Then blame the Republicans for dividing the country, and mock anything and anyone who doesn't do what they're told by the liberal elites.
Basically, they take the minority vote for granted and make them feel smug and righteous while they are doing it, and try to make whitey feel ashamed.
People are flocking to Trump because he ignores the Democrats mocking and doesn't apologize to them. I hope he is able to sustain his momentum.
