A plurality of Americans supports gay marriage. A new POLITICO/George Washington University Battleground Poll found 40 percent of those surveyed said that same-sex couples should be able to be legally married. Thirty percent thought same-sex couples should be able to enter into civil unions but not be allowed to get married. And 24 percent said they should not be allowed to have any type of legal union. The poll of 1,000 likely voters was conducted Dec. 2-6, just before the U.S. Supreme Court’s Friday announcement that the justices will consider two same-sex marriage cases. One in five surveyed admitted to changing their view on same-sex marriage in the last few years, as President Barack Obama said he did earlier this year. Nearly half, 48 percent, approved of Obama’s handling of the gay marriage issue. Seventy-one percent of Democrats approve, and 65 percent of Republicans disapproved. Independents approved the president’s handling by a 16-percentage-point margin, 50 percent to 34 percent.
