Can you find one source claiming his rallies were comprised of paid actors for me, please? It just feels to me like you are talking shit about Trump because you dislike him, but have absolutely no substance to back that up in this instance.
Trump is obviously going to have a big numbers at his rallies.
A LOT of people really, really like him.
...but a LOT of other people really, really don't like him.
He's more divisive than Thatcher, and that's saying something. So of course Trump's hysterical fans are going to pack out his rallies, some of them act like he's the second coming.
Biden is more middle of the road. People will vote for him because they like him or, more likely, because he isn't Trump. But he doesn't invoke the strong passions that Trump does.
Is there any evidence that rally attendance has any correlation with voter turnout or election results?
This is another "statistical anomaly" which isn't one because like all these "anomalies" it starts with a false premise - that rally turnout and voter turnout are correlated.
Is that true? And even if it is, the pandemic was clearly a factor last year which is a confounding factor.
