New Jersey just became the 14th state to legalize gay marriage. This is a development that would have seemed impossible just a few years ago.
Consider this: A Washington Post/ABC News poll earlier this year showed that 58 percent of Americans approve legalizing gay marriage and only 36 percent oppose it. In 2003, it was the reverse: 37 percent favored same-sex marriage and 55 percent opposed it. How did we get here? Let's take a trip down memory lane...
