In a public radio interview Tuesday morning, Gov. Mark Dayton said that he would be "willing to look at" a contraversial measure to require voters to present photo identification before they vote.

As he has before, the governor said he would insist that any election law overhaul would have to include more frequent disclosures for candidates and groups that spend on politics. That proposal hasn't been much loved by Republicans who control the Legislature.

"I've said on voter id, I'm willing to look at it," Dayton said on MPR Tuesday.

The governor's seeming openness to the Republican proposal is notable, given the opposition from many Democrats and their interest groups.

Dayton's had unkind things to say about the proposal in the past and advocates' claim of voter fraud.

"I think this has been a greatly exaggerated phenomenon by those who are dissatisfied with the political results of the last two elections in Minnesota. It is very unfortunate that they are casting aspersions on the integrity of our election process in Minnesota, which I think has been completely upheld by the last two very careful recounts," Dayton said in February.

He has always stopped short of saying he would veto the proposal, as he has with most -- although not all -- legislative bills. That stance could leave advocates unclear on exactly where he stands.

Update:

This afternoon to reporters, Dayton expanded on his views about the measure:

Q: You also said today, again, that you'd be willing to look at photo id. What is there to look at?

Dayton: "I wasn't up to date on what the specifics of the proposal are. It hasn't come up in over a month so I'm willing to look at anything but I'm a long ways from supporting it…I haven't changed my views on it at all. But it came up and as I said I hadn't given it any thoughts since then. But I'll look at anything but I did stress what was the requirement about the financial reporting.

Q: Some of your allies have been surprised that you are willing to say that you are willing to look at photo id. They are steadfast against this. Have they said anything to you?

Dayton: "I haven't had any conversations with anybody. As I say the first time it had come up in over a month was the interview this morning. So think I've said I'll look at just about everything. That doesn't mean I'm going to support it. "
