**"Likely voters" means :** People who have voted in the past.

That does not account for first time voters, like immigrants who just got their citizenship, young who just turned the legal voting age and a lot of other people who did not used to vote but who have registered for the first time like women who are angry at the overturning of Roe v. Wade.

I believe that many Harris voters are not even being counted because the polls only reach out to "likely voters".
