Just after the Goodridge decision, a Boston Globe poll showed that Massachusetts residents backed gay marriage by a margin of 48 to 43 percent. Today, the tide has turned, with 53 percent of Massachusetts residents opposed to same-sex marriage, and only 35 percent in favor. That is a dramatic and important shift. True, polling on the gay marriage issue needs to be taken with a grain of salt. Opinion on this question is highly volatile. More important, the press has prevented the public from hearing good arguments against gay marriage, and this distorts the numbers. In any case, the shift of opinion in Massachusetts is significant, and could have real implications, both for the battle over a state constitutional amendment, and for the national battle over this issue as well.
