The atmosphere created down south is one of hatred and antipathy towards each other, where conspiracy theories are stoked by the President and his lickspittle lackeys, and where the two sides are coming to view each other as the enemy of the nation. That appears to be a view the Republican leadership is content to embrace. If you look at some of the Republican supporters on the internet as an example, these people believe everything they're fed, still believe Clinton is a criminal that somehow the largely Republican FBI refused to properly investigate, that Obama was a foreigner, a Muslim and probably a communist, and that George Soros, who also had a bomb sent to him, is a nefarious Jewish Communist conspirator trying to destroy America and all that is good and right.
I don't really know what can be done to combat this since the amount of money flowing into various bullshit propaganda outlets is so great, so secretive, and so unaccountable. Without that money there wouldn't be the number of crazy people in political office (all of them Republican) that there are now and this
**** would have less weight behind it.
