I really hate being right about the worst fucking stuff.
Biden should never have been put up again, and his performance is gonna enthuse absolutely zero non-political-junkie normies to vote for him.
With states being as voter-suppressed/gerrymandered (or however you prefer to describe the electoral college bullshit) as they are, Dems cannot afford to be slightly ahead. Hillary was slightly ahead. You have to be WAY ahead, and Biden's not.
