There already is a portion of the Democratic party that is so far left that they've lost all resemblance of sanity and rationality and that includes those of "The Squad" and Bernie Sanders types. They are actively rebelling from within the party and seeking others, like-minded to themselves, to "primary" other Democrats whom they perceive as moderate or right of their beliefs. Some call them progressive while others label them as socialist but I believe they are more akin to communist than socialist and I fully believe if they had their way the existing Constitution would be scrapped and replaced with some manifesto or radical document giving all power to the government as they seek total control over their constituents, people, subjects.
The current run, by Bernie Sanders, for President very well may open wounds existing from 2016 when he obviously was cheated by Hillary and the Democratic Party even though if left alone, then, he most likely wouldn't have won. Still, his supporters will and do, remember being Hillary'ed. These are not only some of the most radical supporters that he has, along with the squad, but they are also potentially dangerous and could be violent (I believe). Some have already been taped/recorded by Operation Veritas saying that potentially re-education camps may be necessary for folks like myself and other Trump supporters, Republicans, and/or Conservatives. Some of these people's cheese has slipped off their crackers (for real).
Even if there are not perceived irregularities in the Democratic primaries, and there have already been with the Iowa Caucus, these uber left radicals may well on their own split from the Democratic party into a fringe party of their own or seek an independent run for the 2020 Presidency. One only has to look at the way many of the older, established, Democratic politicians are responding and acting today to see how much influence these new socialist Democrats have. It could even be argued that Nancy Pelosi is SINO (Speaker in Name Only) due to her actions in responding, or reacting, to the new group of Democratic freshmen/freshwomen. Her time and influence are surely limited as the younger Democrats began to take, and yield, power from the establishment.
Actually a split may be the best thing for the Democrats and the nation because it would force people/voters, who now vote and support anything Democrat, blindly to take a position on which fringe section to actually support and why. IF they stay together and don't split then we could, very well, see a day when a socialist (or quasi Communist) is elected to a position of power. So many Nations fall from inside rather than external threats and what with so many having been educated (or lack of it) from highly liberal educators and professors they don't recognize Communism as dangerous or threatening. It would be a definite move toward totalitarian rule where one move would be to eliminate elections altogether. Adam Schiff already, in his presentation to the Senate has accidentally revealed the Democrat desire to stop elections that they perceive they have no chance of winning. Elimination of elections or elimination of the Electoral College is one and the same to eliminate a fair election process.
The electoral college exists, as it is, to make elections fairer and give more representation to smaller states and areas whereas if the Presidential election was only by majority vote you'd never see Politicians or Candidates in States other than New York, Texas, California and potentially Florida and/or one or two other states. Another move, by some Democrats, to eliminate power from the people is the move or notion to increase the number of Supreme Court Justices when Democrats gain power once again in all branches thereby ensuring that they can control the Judicial branch as well.
