It's a given you would have a tough job of finding non controlled media at his shit. Couple of those links have the same data, so it's probably campaign distributed to all sources, which isn't insidious in itself, that's how media works.
At least you pulled up some sources, red as they are.
The paid people behind him are still a joke and I haven't seen Biden do that. They stand in the sun and pull up signs on cue as well as people have numerous signs with them to switch when told. They can be seen in the longer video behind them. And I've seen the same people many many times.
And of course all the camera shots in most the links and vids are carefully framed not to give one the full picture. They never never do that even before 2020.
I've seen more people at outdoor auctions. Then again, there were a lot more tents there for a small merch sale would require, so I'm with Arizona and don't believe all the tents were the campaign.
But I'm not a shittypants supporter so I'm not going to believe a thing he does anyways. He's as stinky as the cow dungs he's set his tent on.
But you can try and support his rallys or play devils advocate all you want, that's your purgative.
