LOS ANGELES (MCT) — President Obama’s announcement of support for same-sex marriage has changed public opinion on the issue, a new survey shows — but only in the most partisan of ways.

Democrats, and especially liberal Democrats, have become more supportive of same-sex couples marrying since the president made his famous pronouncement in May, according to poll results released Tuesday by the Pew Forum on Religion and Public Life. Latinos have also shifted slightly toward acceptance of same-same marriage.
