It was literally like the first really cold day after the first decent snow storm this winter in New England, and it's a weekday. I wouldn't have gone even if I knew who the hell he is.
The primary candidate has already been chosen for the Democrats. Biden is probably the only candidate that stands a chance against Trump which is pretty fucking sad.
He's the only one who stands a chance because he's effectively demanding the nomination (not an unusual stance from the party's incumbent). Any prominent Democrat could beat Trump, and probably more reliably than Biden given the polling and his unfavorables, but no one of stature will challenge Biden and risk splitting the party. Biden is not our best chance, but he's the only chance we're going to get.
