“Then why isn’t Bernie leading in the primary process?”
because bernie publicly declared he’s a hard core leftists and was rejected by the voters for that reason, while biden pretended he was a moderate
however, once biden became the presumptive “moderate” nominee, all of the other avowed hard-core leftist moved into his campaign as “advisors” because biden is totally senile and clueless about what is really going on and essentially now has no other function except as witless front man for the hard-core left; consequently,
1. biden “appointed” AOC as his future energy and climate change czar
2. biden “appointed” uber-anti-gunner Beto as his future gun control czar
3. biden just hired the chief public affairs officer for uber-left-wing MoveOn.org as a senior advisor
those are just the ones that they’ve publicly announced, and more of the same is EXACTLY what we could expect should biden win the presidency ...
that’s why ...
He is more a class-based leftie fighting for the working man than the identity-based lefties that he sees surrounding Biden. His take is that the identity politics is just a cover so that people like Obama and Biden can get credit for being progressive without really helping out the working poor. His big gripe with Biden is that Biden won't go for single payer or universal Medicare.
I don't think he's being paid to spout a line. And it does make sense that made liberals who want to keep their ill-gotten gains don't want to see too much of that money siphoned off by real people. Also makes sense why they are in cahoots with the RINOs of the cheap labor express to keep the borders open.
The Bernie Bros are not happy with Biden. They see the same reports as we do and they don't see that their progressive ideas are being smuggled into the Biden campaign. They feel betrayed.
If this is all some clever plot, then the Bernie Bros will sneak out to the polls and vote for Biden, but I think they're gonna vote Trump, vote Green, or stay home.
