Candidates stepped into the void. Pete Buttigieg went first by claiming victory — misleadingly, in the view of Bernie Sanders, whose campaign responded by releasing unofficial figures showing his strength. Amy Klobuchar also joined in by citing unverified results she said demonstrated a robust performance.

The biggest “winner” might have been Joe Biden. According to the Iowa entrance poll, he was hovering close to the viability threshold of 15 percent statewide. But the questions surrounding the vote-counting served to obscure a potentially poor performance. The former vice president, facing potentially ugly headlines going into New Hampshire and beyond, couldn’t get out of Iowa fast enough…

Conversely, it might have delivered a blow to Sanders and Buttigieg, who appeared on track to do well in the state. Whether the victor turns out to be Sanders or Buttigieg or someone else, that candidate was denied the chance to give an election night victory speech to a nationwide audience — a springboard heading into New Hampshire.

The disarray dealt a huge black eye to Iowa, which was already struggling to defend its coveted first position on the primary calendar. Democratic campaigns grew more furious as the night wore on with no word.
