It’s been well publicized how America has “evolved” on marriage equality. Washington Post/ABC News polling last year found that, by a margin of 58 percent to 36 percent , people believe their fellow Americans should be able to marry whomever they choose — something that would have been unthinkable less than a decade ago.

This progressive trend isn’t isolated to this issue. Over the past 10 or so years, national polls have shown that the general public is becoming more liberal on:

-Immigration. The last time the nation considered immigration reform, in 2006, 52 percent of respondents told Gallup that the priority should be halting the flow of illegal immigration. Just 43 percent preferred to deal with the undocumented immigrants already here. When Gallup asked the same question last July, the numbers had flipped: 55 percent thought the focus should be on immigrants already here, while 41 percent said the priority should be strengthening U.S. borders.

-Marijuana. In 2000, just 31 percent of Americans believed marijuana should be legalized, Gallup found, and 64 percent were opposed. The pro-legalization number has since tracked steadily upward. In October Gallup polling, 58 percent of respondents favored legalization and just 39 percent were opposed.
