I am pretty sure not a single person voted based on something they saw on Facebook on any other social media. It is just a dead horse being beaten over and over by people that still cant believe they were wrong about the election. They have to somehow "fix" the problem. But in reality they still don't get it or cant bring themselves to accept it which means they cant fix it and Trump will win reelection.
People have to accept the result and understand it to overcome and defeat it. It is sad to watch the meltdown and attempt to blame everything but the problem itself. The D's lost for at least 3 reasons. 1. the candidate was really so bad anyone could defeat 2. Trump routed around traditional media so they could not control his message 3. A conservative candidate always wins US presidential elections.
Go back and look at debates even with Obama and Romney. Obama was against gay marriage, talked like a war hawk about Iraq, on and on. He was seen as conservative by the general public. Romney was portrayed by the press as weak. Liberals that supported Obama ignored all of those comments as just lip service and knew about his many other positions. The general public watching CBS news would never see Obama as anything other than an acceptable conservative. Once elected he had more freedom to be himself for the second election.
As of now I predict a second Trump term. Mainly because his opponents are all still focusing on games they cannot win, controlling social media, impeaching the pres, etc. If you have any critical thinking brain cells left you should be able to see those things are not going to happen. The internet will route around censorship. Actually arresting or trying to take down the president will not happen. I would bet any amount of money on that fact. People that still think that might happen are dumber than dumb, I don't care what evidence they think exists, it is irrelevant.
The only way for the Ds to win the next presidential election is a very conservative appearing person that is a fantastic public speaker that does not trash Trump but appears smarter and more pragmatic. I am willing to bet they will go the opposite direction and pick a liberal professor type that complains about everything trump. They will lose bad once again.
Midterms are not an indicator of anything. The opposing party almost always comes into power during midterms because they are reeling from the loss and more motivated to go vote.
