They’re still narrowly against it with 45% opposed and 42% supportive, according to a new research from Public Policy Polling. But that three point margin represents an 8 point shift from last September when 48% were opposed and just 37% in support.
This very much looks to be an Obama effect. Republicans and independents have moved very little on the issue but Democrats have moved 20 points from +15 support (48/33) to +35 support (61/26). The most dramatic movement has been among African Americans who’ve shifted 48 points from being opposed -30 in the fall (23/53) to now supporting it by 18 points (49/31).
