And the circular reasoning starts again. Why did Buttigieg and Klobuchar end their campaigns just days before Super Tuesday?  That wasn't the voters, that was the candidates.  Buttigieg claims to have won in Iowa, Klobuchar was rejuvenated after New Hampshire.
Klobuchar dropped out just before her home state, Minnesota, votes on Super Tuesday — paving the way for Biden to capture a greater share of moderate Democratic votes against Bernie Sanders, who gained momentum and took over the delegate lead in the primary after wins in New Hampshire and Nevada last month. Sanders' surge and Biden's resurgence also pushed Pete Buttigieg and Tom Steyer from the presidential race over the weekend, amid pressure from top Democrats to consolidate behind a Sanders alternative. - Politico
