If you actually read the poling data, most Bernie supporters voted for both Hillary Clinton and Joe Biden in the general election. This Bernie bro bullshit is a lie made up by Clinton and her associates when she blew the 2016 election.
It’s not though. Yes, the two are not only diametrically opposed in their political beliefs but their actual commitment to public service as well. But when Trump first ran he was just a reality TV star, being backed by the GOP machine of course. The real difference is that in contrast, the DNC would likely do everything in it’s power to sabotage Stewart if he tried to run like they do with any and all progressive leaning people.
The news isn’t that the Democratic party is bought and paid for by the oligarchy. The news is that Bernie has stopped playing nice with the DNC.
