This is ridiculous harassment and unneeded extra staff & costs in voter precincts. My Family members are Election Judges in another blood red state! They know their job! This motion by MNSC is meant to slow voter process, possibly close & consolidate venues, and a total witch hunt. It is bullsnot!

Also, personally owned AVs will do a lot of deadheading (driving around empty).

Ex: This study found future AV owners could reduce parking expenses by directing their car to drop them downtown and then drive to the suburbs, waiting to be summoned.

In case you're wondering, the DFL currently has a 7-0 appointment majority on the MNSC.

Taniel @taniel.bsky.social · Apr 7

The Minnesota supreme court's chief justice, Natalie Hudson, is retiring. She first joined the court in 2015 via an appointment by Governor Dayton.

Governor Waltz will appoint a successor (not subject to legislative approval) & then there'll be an election for the seat in 2028.
