Republicans rapaciously enrich capitalists without ethical limit and regardless of damage to others.
Democrats, by contrast, often retain a sliver of concern about a variety of constituencies, including working people, women, and people of color, thus tempering the exploitation and disenfranchisement Democrats advocate. Democrats and Republicans are good cop, bad cop, so to speak. As good cop, at election time Democrats claim to serve various constituencies as a way to plead for those constituencies to vote Democratic. Republican bad cops openly redistribute wealth upward while cutting general supports that might ease derivative suffering. As a result, they have an electoral problem.
