Biden's party is more progressive, but Biden is not. Note how he is on par with popularity polls with the guy who attempted to lynch our political representation. Obama was easily more progressive.
Edit: migrating my response to a deleted comment so others can read it. The deleted comment below accused me of not reading the article. This was my response.
Sure did. It’s an embarrassing op-ed. Short and flimsy arguments. Every link is either something that someone else did (mostly state legislators) or about lip service rather than action. About the only thing Biden can claim credit for is related to the economy, where his policy has helped transfer wealth upward. If “progressive” means “keeping things perfectly as they are” then you can go ahead and be a progressive.
