A Minnesota election rule that lets a single registered voter vouch for other people without ID is drawing fire, and it is bad news for anyone who wants tighter ballot checks.

• Minnesota allows voters without ID to register at the polls if someone else vouches for them.
• A local election worker confirmed one person can vouch for as many as eight others.
• Critics call the setup an open door for fraud, since the voucher effectively becomes the ID.
• The exact limit is fuzzy even among people running elections, which fuels the distrust.

Outlook: Expect louder calls to scrap or tighten same-day vouching in Minnesota heading into the next election cycle.
