(AP) – President Barack Obama on Thursday threw his support behind ballot measures in Maine, Maryland and Washington state that would legalize same-sex marriage. Though the president first voiced his general approval for gay marriage in May, he had not previously offered specific endorsements of the three measures. In each case, the endorsements were issued through the state branches of Obama’s re-election campaign.
