From “Joe Biden’s Poll Numbers Mask an Enthusiasm Challenge,” an 8.22 N.Y. Times story by Katie Glueck:

“A Monmouth University poll from this month showed Mr. Biden leading with the support of 28 percent of likely Iowa caucusgoers — virtually unchanged from the same poll’s results from April.

“But Patrick Murray, the director of Monmouth’s Polling Institute, who recently spent time in Iowa, said those numbers did not give the full picture of Mr. Biden’s support in the state.

“’I did not meet one Biden voter who was in any way, shape or form excited about voting for Biden,’ Mr. Murray said. ‘They feel that they have to vote for Joe Biden as the centrist candidate, to keep somebody from the left who they feel is unelectable from getting the nomination.'”
