If only there was any evidence at all. Trump could only find 50 people incorrectly registered to vote in all of California. They still check your registration at the polls too.
There is tons of evidence! When Texas does its biannual purge of voter registrations from blue zip codes, all the people who silently had their right to vote revoked generate statistics when they try to cast a ballot.
Kinda like how you can point to an essentially arbitrarily large quantity of illegal immigrants if you first manufacture them by revoking their ability to be here legally, without informing them.
