GOP backers of a plan to require photo IDs at the polls are considering an effort to seek a constitutional amendment if the bill is thwarted by a veto.
The controversial voter ID bill is nearing a floor vote after months of hearings and while Gov. Mark Dayton said Tuesday he is willing to look at the bill, he added he is a "long ways from supporting it."
But GOP legislators leaving the Capitol for an Easter break are touting the measure as one of their signature policy proposals of the session, explaining why some lawmakers are crafting legislation that could put it on the ballot in 2012.
It faces strong opposition from groups who say it could hinder some Minnesotans from voting.
The so-called "voter ID" bill would require registered voters to show Minnesota photo identification to vote and would eliminate vouching as a method for Election Day registration.
It also would create an entirely new system of provisional balloting, in which challenged ballots would not be not counted until voters can supply proper identification. To accommodate voters without driver's licenses, the state would begin offering free "voter identification cards."
Minnesota law does not currently require voters to show ID if they have already registered. Nine states do require photo identification to vote and several others are considering such measures.
Supporters say the changes are necessary to prevent voter fraud, which critics dismiss as largely nonexistent in Minnesota. Opponents charge that new requirements to have a Minnesota ID with a current address will disenfranchise seniors and college students, who often do not have up-to-date identification.
