Vermont has become the fourth state to legalize gay marriage — and the first to do so with a legislature's vote. The Legislature voted earlier today to override Gov. Jim Douglas' veto of a bill allowing gays and lesbians to marry. The vote was 23-5 to override in the state Senate and 100-49 to override in the House. Under Vermont law, two-thirds of each chamber had to vote for override. The vote came nine years after Vermont adopted its first-in-the-nation civil unions law. It's now the fourth state to permit same-sex marriage. Massachusetts, Connecticut and Iowa are the others. Their approval of gay marriage came from the courts.
