ST. PAUL (WCCO) – A new poll suggests Minnesota voters may reject a proposed constitutional amendment that would define marriage as only being between one man and one woman.

On Tuesday, Public Policy Polling announced new numbers indicating that 49 percent of likely voters would be opposed to the amendment. The poll suggested 43 percent were in approval of it.

PPP said those numbers represent a swing from their January results, which showed the amendment passing with 48 percent in favor and 44 percent against.

The new poll numbers show movement among likely independent voters, from 50-40 in January to 54-37 now.

The poll results came from a survey of 973 voters polled on the telephone between May 31 and June 3. The margin of error was listed at 3.1 percentage points.

Public Policy Polling was founded by a Democratic pollster, but has also been reported to have a slight pro-Republican bias in polling results, according to some analysts.
