The day before citizens in Mississippi go to the polls, a new survey indicates a dead heat in a ballot initiative that would make the state the first to amend its constitution to define all human life as beginning at conception, according to Baptist Press. The poll of 796 likely voters, conducted over the weekend by Public Policy Polling, has Initiative Measure 26 leading, 45-44 percent, with 11 percent undecided. "Right now it looks like it could go either way," Public Policy Polling said in an analysis. Initiative 26 is a direct challenge to Roe v. Wade, the 1973 Supreme Court ruling that legalized abortion nationwide, and if passed, it would end abortion in Mississippi. Colorado voters rejected a similar proposition in 2008 and 2010, but Mississippi's more conservative voter makeup gives such an amendment more of a chance for success.
