The fate of Minnesota’s Voter ID constitutional amendment hinges on the November elections in more ways than one — and it could be procedurally defeated even if approved at the polls, according to some experts. Democrats may get a final chance to soften the blow they say the measure would cause voters if it truly became part of the Minnesota Constitution. Republicans will have to watch the gamble they took in deciding to bypass the governor and to leave the specifics of a Photo ID system to the next Legislature. The amendment, which polls show highly favored by the public, would require voters to show a photo ID in order to cast a ballot. Despite highly publicized campaigns against Voter ID, many opponents seem resigned to the likelihood that it will pass. But even if it does, it would be up to the next Legislature to fill in the statutory blanks of how the system would work, since the wording of the bite-size amendment speaks only in generalities.
