He did this before without campaigning. He’ll do it again by hook or crook. Fox News poll has Biden up over Trump.
(I know, I know. Every poll is fake, fraudulent, and sponsored by deep state unless the poll results support the candidate of your choice)
Not Biden personally - but those running the Biden campaign ran circles around the Trump campaign and crushed them. That is reality. On many media outlets the Biden campaign was ubiquitous and the Trump campaign was completely absent. Biden's campaign was targeting senior voters and those who voted third party in 2016 to feel "comfortable" with good ol' Joe unlike how they felt about Hillary. This is not even counting the fact the Democrats were already experts at "ballot harvesting" and the GOP was behind the curb. You can't win if your opponent is the only one showing up to the battlefield.
