Nobody here gives a shit about polls. Do you think his crowds are getting bigger or smaller? From whats been posted here, they look pretty slim, but I suppose that could be this site's bias.
You're not paying much attention. There is poll after poll posted ITT.
Biden had no crowd sizes in 2020, and still got a ton of votes, 81 million or not. Normal people don't go to political rallies 6 months before elections, and most aren't thinking about politics.
