Every good pollster will tell you that a poll is merely a snapshot in time. That may mean no one should read too much into today's Field Poll showing a slim majority of Californians now support same sex marriages. After all, opinions change.
But another argument may be made that this is far from a fleeting development, as support for the idea has slowly but measurably grown. And that theory can be backed up by more than 30 years of surveying on the issue by respected pollsters Mervin Field and Mark DiCamillo.
Today's headline is clearly the poll results showing 51% of voters surveyed approve of gay marriages, while 42% oppose them. The poll will be online here later today.
But beyond that is some fascinating data about how the issue has changed over time. First, the historical context. In this poll, and six others dating back to 1977, Field asked the following question (used verbatim every time in the past 31 years):
Do you approve or disapprove of California allowing homosexuals to marry members of their own sex and have regular marriage laws apply to them?
Only 28% of adults agreed with that statement in 1977. By 1997, it was 38%. In 2004, 44% of voters agreed. Today, it's eeked over the majority line at 51%.
So what's going on? No definitive answers, but some reasonable theories:
1. Young vs. Old: The generation gap on this issue is now enormous. Field's new poll finds those between the ages of 18 and 39 strongly favor same sex marriages, while those 65 and over strongly reject them.
2. Urban vs. Rural: The familiar schism in California politics is holding true on this issue. Los Angeles and the Bay Area approve in the new poll, while voters in the Central Valley and Inland Empire generally do not. The divide is roughly the same when breaking the state down by coastal counties versus inland ones.
3. Religion: In one of the more controversial and murky areas of the poll, more Catholics and Protestants surveyed disapprove than approve. And those describing themselves as born-again Christians strongly reject the concept, 68%-24%.
As you might expect, the other big attention-getter in this poll is the fact that the likely November intiative to amend the state constitution and ban gay marriage looks to be in trouble before it even qualifies for the ballot. Regardless of how the question was asked (and it was asked two different ways), at least 51% of registered voters said they oppose such a plan. Field notes that the findings mirror other surveys on whether the issue should be amended into the U.S. Constitution -- perhaps that major step is the problem.
But one particular item stands out in my quick analysis, and it's the growing acceptance of same sex marriage among California's new power players in state politics: the indepedent "decline to state" voters. In Field's August 2003 survey on the issue, just 50% of these voters said they approved of gay marriages. This time around, support among decline to state respondents is at 61%.
Remember, this is the single fastest growing group of California voters -- now almost 20%. This is also the group that has been closely tied to the political fortunes of Governor Schwarzenegger, who has said he will oppose the initiative if it makes it to the ballot. The convention wisdom is that most Democrats support same sex marriage and most Republicans oppose it. But the real action, to borrow a phrase from the guv, is with non-partisan voters. And they may hold the key to whether California takes the national lead on this issue in November... one way or the other.
