This is a dangerous man with a dangerous proposal involving a dangerous person. Anything that would give AOC more power or political say is dangerous to our Nation and Democracy. These are both people who are politically inclined alike and would have no problem if the Constitution was to burn up allowing them to replace it with some totalitarian administration/government.
While I don't think Bernie stands a chance one never really knows because I have all assurance that there are a large number of voters who will vote Democrat regardless of who the candidate is or what the candidate proposes and believes. Their vote is cast not based upon the positions or the candidate but rather solely on the party that the candidate is affiliated with, so it's theoretically possible there is a path for Bernie, and AOC, to make it to the White House or even anyone like them.
