On Nov 7, the Democrats will have lost seats in the Senate and made only slight gains in the House. The two years of constant hate Trump pouring from the media and all the Democrat political smear games will have failed. However, the Democrats have veered so far left and have stirred up the radical base that things will get out of hand and turn violent at the least provocation. I expect Ruth Bader Ginsberg will not hold on until 2020 and will die or become incapacitated in the next year giving Trump another Supreme Court vacancy to fill. This will set off political riots with leftists burning cities, committing acts of terrorism and possibly political assassinations. This will be worse than 1968 and the radicals having been defeated by legal means to oust Trump will seek revolution to violently overthrow the government. This will not end well and will approach all out civil war with the involvement of US troops and the possible declaration of martial law. The radicals and their enablers could be facing military tribunals on charges of sedition and treason.
I don’t think that will happen. The 1960s had genuinely motivated people (who didn’t want to go to Vietnam). The current “resistance” is entirely paid and fabricated. Trump will break them.
