NEW YORK (AP) — Pete Buttigieg is clinging to a slight lead over Bernie Sanders in a new batch of votes released by the Iowa Democratic Party. The race remained too early to call with 75% of precincts reporting by Wednesday afternoon, almost two full days after the state hosted its first-in-the-nation presidential caucuses. Much of the political world has already shifted its attention to New Hampshire, which votes on Tuesday.

Wednesday’s updated results show Elizabeth Warren, Joe Biden and Amy Klobuchar trailing. Iowa officials attributed their delay to technical problems. The chaos surrounding the reporting breakdown has undermined the impact of Iowa’s election, which typically rewards winners with a surge of momentum.
