Last Friday, the U.S. Supreme Court agreed for the first time to take on the issue of gay marriage. No matter how it rules in the two cases it will hear next spring, polling data suggest it is only a matter of time before legal recognition of same-sex unions is the norm throughout the country.
Something similar is happening with marijuana, which became legal in Washington last week and in Colorado on Monday. With both pot and gay marriage, familiarity is breeding tolerance.
The cases before the Supreme Court deal with popular reactions against gay marriage: the Defense of Marriage Act (DOMA), a 1996 law that barred the federal government from recognizing state-licensed gay marriages, and Proposition 8, a 2008 ballot initiative that amended California's Constitution to eliminate same-sex couples' right to marry, which the California Supreme Court had recognized that year. But something interesting happened after those measures passed: Surveys now indicate that most Americans support gay marriage.
The turnaround was remarkably fast. A 1996 Gallup poll found that 27 percent of Americans thought same-sex marriages should be "recognized by the law as valid, with the same rights as traditional marriages"; by last year, that number had nearly doubled. Recent surveys by ABC, CBS, NBC and CNN also put support for gay marriage above 50 percent.
Striking generational differences mean these numbers will continue to rise. In a CBS News poll last month, 72 percent of 18- to 29-year-olds supported gay marriage, compared to 53 percent of 30- to 44-year-olds, 44 percent of 45- to 64-year-olds and 33 percent of respondents who were 65 or older.
The consequences of these changing attitudes could be seen in last month's election results. For the first time ever, gay marriage was legalized by popular referendum -- not in one state, but in three: Maine, Maryland and Washington. Voters in a fourth state, Minnesota, rejected an initiative that would have amended the state constitution to prohibit gay marriage (which is already banned there by statute).
On the same day, voters in Colorado and Washington approved ballot measures aimed at legalizing the cultivation, possession and sale of marijuana for recreational use. The initiatives won by surprisingly healthy margins of about 10 points in both states, in contrast with a California legalization measure that lost by 7 points two years ago.
