Nasty flaw in Minnesota mail ballot process

There’s a nasty flaw in Minnesota’s vote by mail process.

When you apply for a mail ballot you are asked to provider either a SSN last 4 or License number or State ID number.

When you complete the ballot you are asked to provider either a SSN last 4 or License number or State ID number.

The two numbers have to match or the ballot will be rejected.

Hope you remember if you used your MN License number or your SSN Last 4 on the ballot application.

I tried testing for the identifier I used by querying my absentee ballot status, but it found the same status regardless of which identifier I used.
