Politico: “Sen. Bernie Sanders and former Maryland Gov. Martin O’Malley are both expected to challenge Hillary Clinton for the Democratic nomination for president… But, perhaps counterintuitively, it’s Sanders — six years older than Clinton, a self-defined socialist with no big money apparatus and positions that appeal to the far left of the party — that Democratic strategists and Clinton insiders expect to pose a bigger threat to the former secretary of state than the mainstream O’Malley, who has been trying to build a national constituency by positioning himself slightly to her left.”
