Like Biden or don't, but he will be the Dem nominee. The alternative is anything the GOP puts out there, likely Trump.
We are a two-party system right now. That's just how it is. Your choice will be Biden v. Trump or someone as bad or worst than him. So, your choice will be Biden or full-on fascism with the possibility of a GOP president actually pulling off a coup next time.
Don't like Biden? Fine. But don't pretend both candidates are equally bad. That's how we got Trump in the first place.
