Support for gay marriage hit 50 percent in states that continue to ban the practice, according to a new poll.
A Washington Post/ABC News poll released Friday found 44 percent of people in those 31 states that continue to oppose gay marriage.
In those states, 48 percent believe same-sex marriage is not guaranteed by the Constitution, while 45 percent believe the Equal Protection Clause protects it.
Overall, 56 percent of all Americans support gay marriage, slightly down from its previous high of 59 percent in the news organization's March survey.
Another 38 percent oppose gay marriage.
Across the nation, 50 percent believe gay marriage is a constitutional guarantee.
The poll surveyed 1,002 people from May 29-June 1 and has a margin of error of plus or minus 3.5 percent.
