POLL: Minnesota Inequality Amendment Race Still Tight | A new Survey USA poll shows that the Minnesota marriage inequality amendment is still hotly contested. According to the latest numbers, 48 percent support the discriminatory amendment, 47 percent oppose it, and 5 percent are undecided. A similar poll two weeks ago found about the same result, 48-47. Both have a margin of error of just over 4 percent, so the change is negligible. Though there seems to be more support than opposition to the measure, it still requires a full 50 percent vote to pass, meaning that those who skip the question on the ballot will be counted as a no vote.
