Bernie Sanders was never a Democrat, except for the brief convenience of running for their 2016 Presidential nomination. He has always been some variety of socialist independent commie, and he announced after the 2016 campaign that he would resume being registered as an Independent.
I actually have some sympathy for the Democraps in this one respect, that Sanders is NOT of their party but was able to hijack their nominating process for a while.
Ofc Trump is not exactly a Republican, and took over their party, but that is for the better!! heh heh....
Yes, they are a party of idiots led by idiots.
