As Democrats oust Iowa from atop presidential calendar, here’s a look at how they got here

Democrats voted this past weekend to say goodbye to Iowa as the first state on their presidential nominating calendar, a move likely to end the state’s almost 50-year history leading off the Democratic race for president.

Iowa has had a strong history of picking Democratic candidates that ultimately win the party’s nomination — Jimmy Carter, Walter Mondale, Al Gore, John Kerry, Barack Obama and Hillary Clinton all won Iowa caucuses the year their party tapped them as its presidential nominee.

But that wasn’t the case in 2020, when Democrat Pete Buttigieg ultimately won a caucus mired by technological mishaps that delayed the reporting of the results for days. It was that mishap, along with concerns from many Democrats about the lack of diversity among the electorate picking winners in each of the first two nominating states (Iowa and New Hampshire) that helped pave the way for this weekend’s vote.
