According to exit polling of the 2012 election, just 5 percent of voters who turned out were gay. Yet voters said their states should legalize same-sex marriage by 49 percent to 46 percent. Indeed, social issues like gay marriage and the media-concocted “war on women” probably gave President Obama his margin of victory.

Consider another figure: According to a May 2011 Gallup poll, most U.S. adults “estimate that 25 percent of Americans are” gay or lesbian. In reality, the number of people who identify themselves that way is just 3.4 percent, according to a Gallup survey released in October 2012. But it’s understandable that so many people might overestimate the number.
