Polls highly favour Joe Biden to win the US presidential election.
These polls are not just abstract information. By telling prospective voters who is the most likely to win, can they influence the result of the election by playing a role in the voters’ decision? The evidence says yes, and it most likely favours Biden.
In theory, you could imagine two possible effects of polls. First, a momentum effect. Second, an underdog effect.
