When I worked in campaigns (local) back in the day we did not ask people if they were registered—we compared their names to registration lists.
People notoriously claim they are registered when they are not, because they want to appear to be “good citizens”.
They lie to friends about it as well.
If you live in a battle ground state, please volunteer to be a poll watcher in your community. One of the best way’s to determine if there has been fraud, is to participate in the exit polls. If they are more than a few percentage points off that is grounds for contention.
We need to keep an eye on our election, don’t let them steal it from us!
ALSO. Remember to wear RED when you vote as an added visual of who is voting for Trump, every little bit helps.
