The 2020 presidential nominating process kicked off on Feb. 3, with both Democratic and Republican caucuses held in Iowa.
Up for grabs were 41 delegates for Democratic contenders and 40 delegates for the Republicans.
Almost a month after the caucuses, the process -- plagued by reporting errors and issues with a new app -- came to an end with the Iowa Democratic Party certifying the results on Feb. 29.
Buttigieg was awarded 14 delegates, Sanders was awarded 12 delegates, Elizabeth Warren was awarded eight delegates, Joe Biden was awarded six delegates and Amy Klobuchar was awarded one delegate.
Though Sanders has mentioned challenging the results, they have been officially certified and there was no mention of the challenge in Iowa Democrats' release.
For the Democrats, a strong finish across the Hawkeye State's 99 counties could establish an early lead for one hopeful, separating that candidate from a crowded pack.
During the last presidential cycle, Texas Sen. Ted Cruz won the 2016 Iowa GOP caucuses with then-candidate Trump finishing second.
On the Democratic side, former Secretary of State Hillary Clinton prevailed over Sanders.
