Donald Trump has tried, with limited success it would appear, to convince African-Americans that they have been swindled by the Democrats, who use their votes but ignore their concerns. I don’t think that is actually true. We can argue about whether Democrats have done enough, or had the right priorities, and to what extent this is just another example of the Republicans blocking progress and then accusing the Democrats of not wanting it enough, not “leading” enough. But the needs of African-Americans — including affirmative action, housing integration, support for the poor — are clearly a significant concern of governing Democrats.
The people who were really used and abandoned by the Democrats were the white racists. The Democrats were happy to have their votes through the 1970s, and then abandoned them as the fraction of non-white voters made the racists seem electorally less significant. Shameful!
