Many members of the US Congress welcomed President Barack Obama's decision to let them vote on military intervention in Syria, but it was unclear whether he would be able to gather enough support, dpa cited the New York Times as saying Sunday. Officials from the Republican Party, which dominates the House of Representatives, said that if a vote were taken immediately, the measure would fail, the paper said. He also faces an uphill battle in the Senate, even though his Democratic Party has a majority. "Obama hasn't got a chance to win this vote if he can't win the majority of his own party, and I doubt he can," the paper quoted leading Republican Representative Tom Cole of Oklahoma as saying. Lawmakers gave different reasons for their opposition. "We are not the world's policeman," Democrat Alan Grayson of Florida said on Twitter. Republican Senators John McCain of Arizona and Lindsey Graham of South Carolina said Obama's plans did not go far enough. "We cannot in good conscience support isolated military strikes in Syria that are not part of an overall strategy that can change the momentum on the battlefield," they said in a statement.
