Hu? Bernie has always been an independent. He changed parties to run for the Democratic nomination in 2015, changed back to an independent in between, and then switched back to a Democrat last year to run again for the nomination.But you'll argue for capitulating and taking money from an authoritarian racist and allowing him into the field while trying to suggest a candidate who has been part of the party for decades and is on the same spectrum as the party should would be equally disqualified (despite the fact i already gave my reasoning for the distinction).
I think if you want to run on the party's ticket you at the very least, shouldnt be oppositional to their positions IE being a republican. I wouldnt call such a stipulation authoritarian either lol
Bloomberg has significantly more years as a Democrat under his belt than Bernie does.
