More votes than registered voters? This is actually easy to find out. Every state keeps a record of who is registered and when they vote.
Did you know that? When you register, you tell the state who you are and where you live.
And then when you go vote, they check that.
This is how they make sure you don't vote more than once.
Did you also know that states make the total numbers available by county?
Yeah, they do. Online in nice spreadsheets. For free.

There was no voter fraud. You have been lied to and you are choosing to believe those lies.
