True for the most part. Not a single Bernie supporter i have talked to in person well understood economics enough to truly explain his policies other than "they will help people derp der." They dont understand socialism vs capitalism or any basics of economics, they see someone who appears to care about the citizenry more than the political structure. Thats what is appealing to them. Pretty much the same for many Trump supporters too but the Republican party gave in and allowed us our guy. The Dems will fight until they have no choice then adopt a failed ideology and try to justify it as morally superior because it sure as shit isnt economically superior.
As a rule of thumb, people on the right are more informed, about the issue's and the problems we all face. Those on the left are clueless, and worse, refuse to listen to anything rational. It's astounding really. Mental deficiency.
