Washington Post-ABC poll shows most Americans are okay with gay marriage. More than half of Americans say it should be legal for gays and lesbians to marry, a first in nearly a decade of polls by ABC News and The Washington Post. This milestone result caps a dramatic, long-term shift in public attitudes. From a low of 32 percent in a 2004 survey of registered voters, support for gay marriage has grown to 53 percent today. Forty-four percent are opposed, down 18 points from that 2004 survey.
