A new ABC News/Washington Post poll finds support for gay marriage is now 58%, a new high, “marking a dramatic change in public attitudes on the subject across the past decade.”
That number has grown sharply… from a low of 32 percent in a 2004 survey of registered voters, advancing to a narrow majority for the first time only two years ago, and now up again to a significant majority for the first time.
Meanwhile, Nate Silver finds relatively low support for marriage equality among Republicans:
[O]nly 26 percent of Republicans support same-sex marriage rights as compared with 54 percent of independents and 66 percent of Democrats. Attitudes among Republican voters may shift on the issue by 2016, particularly if more respected conservatives like Mr. Portman announce their support for same-sex marriage, but it is less than clear that his position will reflect a broadly acceptable viewpoint among Republican primary and caucus voters by that time.
