Popular support for gay marriage has been rapidly increasing in the last two years, and several polls now show that support for gay marriage is a plurality or majority position in the American public, according to research by Nate Silver. This shift in public opinion is happening far too rapidly to be due to generational replacement, so it must be the case that many people have changed their minds. What could be the reason for the sudden shift in many Americans’ views? Silver points out that parties and candidates are placing less stress on opposition to gay marriage than they once did, creating a feedback loop in which public opposition to gay marriage further softens. It may also be that once public opinion reaches a tipping point at 50%, opposition rapidly declines because Americans don’t wish to see themselves as being on the losing side of history.
