“[Biden] is still viewed as someone who’s had a very long career in government and politics, and I think there’s a recognition of that lengthy career,” said Lesley DeNardis, executive director of Institute for Public Policy at Sacred Heart University and the poll’s director. “I think voters weigh that against more recent gaffes of his on the campaign trail. And I think he does prove to be a more centrist candidate than some of the others. That also puts him in good stead with the voters.”
