(CNN) - Maine lawmakers Wednesday voted to make same-sex marriage legal in the state, the state Office of Legislative Information said. The bill now goes to Gov. John Baldacci for his signature or veto.
Baldacci, a Democrat, has not said whether he will sign it.
"He's going to make a decision when it hits his desk," spokesman Dan Cashman told CNN immediately after the vote. He said the governor is likely to make a statement later in the day.
Three states - Massachusetts, Connecticut, and Iowa - currently allow same-sex marriages. Vermont has passed a law making gay and lesbian marriages legal. That bill takes effect in September. New Hampshire lawmakers are close to passing a similar bill.
A slim majority of Americans are against legal recognition for same-sexmarriage, CNN polling found last month. Fifty-four percent of adults questioned in an April 23-26 nationwide CNN/Opinion Research Corp. poll said that marriages between gay or lesbian couples should not be recognized as valid, while 44 percent said they should be considered legal.
The survey's sampling error was plus or minus 3 percentage points.
