President Barack Obama's gay marriage nod appears to have stoked both supporters and opponents of equal marriage rights for gay and lesbian couples.

Obama came out in favor of gay nuptials the day after North Carolina voters approved a constitutional amendment which defines marriage as a heterosexual union and bans the state from recognizing gay couples with marriage, civil unions and possibly domestic partnerships. The president made his historic endorsement after years of signaling that he was “evolving” on the issue.

According to a poll released Friday by the Associated Press-GfK, Obama's endorsement last month did little to shift Americans' views on marriage equality.

Opposition to such unions dropped only 3 percent from a similar poll conducted last August, moving down from 45 to 42 percent. But support also fell, from 42 to 40 percent.

Approval of the president's handling of gay marriage increased among respondents who identify as Democrat or liberal. Last year, only 16 percent of Democrats approved. That number increased to 41 percent in the new poll. Similarly, approval among liberals increased from 28 to 48 percent.

The reversal is true on the right, where Republicans and conservatives increasingly disapprove of the president's handling of the issue. Disapproval increased 8 percent among Republicans, from 45 to 53 percent, and 9 percent among conservatives, from 43 to 52 percent.
