The Christian Science Monitor has an in-depth article about the current state of gay marriage in Massachusetts. The most recent polling indicates that 62 percent of Massachussans oppose amending the constitution. But there's an odd thing about polling related to discrimination: People lie. They are embarassed to tell a pollster that they will vote to quash the rights of minorities, but in the privacy of the polling booth the temptation to do so can be great. In the days just before the November election, an Arizona pollster told me that only 30 percent of those surveyed supported the Arizona anti-gay marriage amendment. The amendment did fail--becoming the first ever to do so--but only by a few percentage points. Popular support at 62 percent is not enough to be free of this phenomenon.
The sound byte for gay marriage supporters in Massachusetts has been that the civil rights of a minority should not be put to a popular vote. After all, as Equal Marriage puts it, "This is the basic guarantee of our constitutional democracy."
