This is a fairly balanced news report from KSTP, Minnesota's ABC News affiliate:

But here's a mystery: it reports the latest Survey USA poll taken May 24th and 25th shows Minnesotans will vote for the marriage amendment 51% to 40% (with 10% "other"). The exact wording is not provided.

But the reporters says this is a steep drop from a poll in March showing 62% of Minnesotans favor a marriage amendment.

We cannot find any mention of that poll on the web. It ought to have been fairly big news in Minnesota. Are we missing some news coverage? If you've seen a March 2011 Survey USA today poll can you send us a link?

If the poll was taken, and the results not reported, that would be very odd behavior on the part of ABC news.
