I’ll concede your point that many things would likely be better. However, only if Mitch McConnell were somehow out of the picture. As long as he sits at the head of the majority party in the senate, there will be no progress on any progressive fronts.
Nevertheless, a lot of people were convinced by decades of right wing smear. Hillary Clinton was damaged beyond repair a long time ago. I know several people who voted Trump because they absolutely did not want a return to the politics of the Bill Clinton era. More than one of them told me face-to-face that they voted Trump because Bernie was their first choice.
We’re in the last gasp of conservative politics. Bill, Hillary and even to a lesser extent Obama all belong to that era. Moderation in the Democrat ranks just gives us more of the same corporate owned government as we’ve been suffering under since the ’80s. The bulk of the younger electorate want real, visible change. And they’re getting tired of waiting.
