They do ask for ID. When you register to vote, your ID is verified. Before every election, voter registration is verified against multiple databases and discrepancies are investigated.

Some voters either need to produce ID or complete an affidavit confirming that they are who they say they are and live where they say they live. This information is noted in the Poll Books and the poll workers - who are elected- are responsible for following the instructions in the book. So, if you think they are committing fraud, consider running for Inspector of Elections yourself and doing the job.

When voters apply for an absentee or mail in ballot they have to provide ID. If they don’t, or voter services can’t verify it, their ballot can’t be counted until it’s verified.

There are multiple reports that have to be reconciled before an election can be certified.

The idea of widespread fraud- whether being asserted by Dem, Reps, Greens or Jedi’s - is equally problematic without evidence.
