MPR reports the near concession. This is a huge deal. Before this year, voter id had been supported in public by both Democratic and Republican voters (though opposed by Democratic elites). This is the year that voter id and the voting wars more generally broke through as a major political issue on the Democratic side on the left.
The defeat of this amendment means that the dispute over ID in the public is now more likely to reflect the split among elites.
More on the backlash over Republican overreaching on ID, early voting, etc. to come.
