Today’s Essential Research survey reports a drop in support for gay marriage since November 2010, from 53% to 49%. Those against are up from 36% to 40%.
The margin of error for a poll like this is about 3% in either direction, so it is possible that there is no real change. But this does seem to be the first poll for several years that has found minority support for same-sex marriage. While the demographics of opinion on this subject leave little doubt that there is an emerging clear majority view in support of same-sex marriage, the campaign for it may experience a few short term ups and downs.
