I don't deny that Bernie is more loved than Biden, but he's also more hated. ~30% of the Democratic Party really, really loves Bernie, and the other 70% is either indifferent or dislikes him. From my perception, Biden is just "meh" for the vast majority of Democrats, but an acceptable "meh."
Either way, it's an uphill battle to claim that the party is controlled by the "woke mob" or "leftists," especially when you just argued that a small group of powerful people can control the entire primary to allow the moderate candidate to win.
