PORTSMOUTH, N.H. — Hillary Clinton seems to be having trouble earning the public's trust.
The Democratic presidential candidate is trying to convince voters that she is authentic.
But rival Bernie Sanders is stepping up his criticism of her Wall Street ties and raising questions about whether she's really a liberal.
His message is connecting with younger people. They seem less interested in Clinton's pitch as a "progressive who gets things done" than in Sanders' call to break up big financial institutions and expand social programs as part of a "political revolution."
According to surveys of Iowa caucus-goers, it appears that questions about Clinton's authenticity hurt her in the state.
Clinton did squeak out a narrow victory over Sanders in the leadoff caucuses last Monday.
Up next is the New Hampshire primary on Tuesday.
