KEENE, N.H. — Hillary Rodham Clinton dismissed swirling questions about her family foundation Monday as little more than political attacks from Republicans eager to gain an early advantage in the 2016 presidential contest. Clinton, campaigning for the Democratic nomination in the liberal bastion of Keene, pushed back against accusations that foreign governments that made donations to the Clintons’ charity received preferential treatment from the State Department while she served in the Obama administration. “We will be subjected to all kinds of distractions and attacks,” she told reporters after a roundtable event at a wood furniture factory.
