The Bernie Sanders moment does not appear to be passing, at least not yet. The latest Quinnipiac poll of of likely Democratic caucusgoers in Iowa shows the Vermont senator trailing Hillary Clinton by 19 points—a gaping deficit, until you consider that just two months ago, Clinton led Sanders by 45 points in Quinnipiac’s Iowa poll. Sanders has improved his position in Iowa, from 15 percent support to 33 percent, but Clinton’s support has eroded, too; the former secretary of state was at 60 percent in early May, and now she’s just holding onto a slim majority at 52 percent.
