Gallup poll: Support for marriage equality at all-time high

Americans' support for laws recognizing same-sex marriages as legally valid has increased yet again, now at 55%, according to the latest Gallup poll.

As has been the case in the past, support for marriage equality is higher among younger Americans; the older an American is, the less likely he or she is to support marriage for same-sex couples. Currently, adults between the ages of 18 and 29 are nearly twice as likely to support marriage equality as adults aged of 65 and older.

Opinions also differ dramatically along party lines. Democrats (74%) are far more likely to support gay marriage as Republicans are (30%), while independents (58%) are more in line with the national average.

While still lagging the national average, Republicans support has nearly doubled since Gallup began polling on the question in 1996.
