You are wrong. Bernie did not elect Trump. The Electoral College did. And if you are looking for anyone to blame personally, then that person is and must be the person who OPPOSED Trump, and then LOST. That is Hillary Clinton.
Please stop spewing this corpdem propaganda line that somehow Berners and the people who want to see change in the Democratic Party are “helping” Trump and the GOP. That is actually the same line of reasoning that fascists and dictators use: if you speak out against us, you are helping our enemies. That is what every authoritarian regime has said from the beginning of time. That is why and how they are able to arrest and kill dissidents.
If the Democrats don’t want to see Trump and the Republicans win then they have to line up behind Bernie and the 80% of their own base that agree with him. But they don’t, and they won’t. They would much rather see Trump win than see Bernie win. That is just fact. Because with Trump and his minions in power, the Democrats can fundraise like crazy. But if Bernie and the Progressives win, that gravy train of big donor money stops running. Open your eyes.
