DES MOINES, Iowa -- In the closest Iowa Democratic caucuses in history, former secretary of state Hillary Clinton narrowly defeated Vermont Senator Bernie Sanders.

As of early Tuesday morning, results from only one precinct, located in Des Moines, remained unknown. The precinct is worth 2.28 delegates and mathematically would not change the final outcome in the race.

But 100 percent of the caucus precincts were reported mid-morning Tuesday, and Clinton was shown to have won the Democratic Iowa Caucus by only two-tenths of a percent. Clinton had 49.8 percent of the delegates while 49.6 percent went to Sanders.

According to the Iowa Democratic Party, Clinton received 700.59 delegates compared to Sanders' 696.82 delegates.

Clinton becomes the first woman in history to win the Iowa caucuses.

But the results were more than just razor-thin in some precincts, it was a tie, therefore deferring to a coin toss, In precincts in Ames, Newton, West Branch, Davenport and two in Des Moines, there were an odd number of delegates, so they couldn't be evenly split into two.

Political reporter for Univision, Fernando Peinado, posted a video to his Twitter that shows a coin toss for a Clinton-Sanders tie.

Matt Paul, Hillary for America's Iowa State Director, released a statement following Clinton's caucus victory.

"Hillary Clinton has won the Iowa Caucus. After thorough reporting – and analysis – of results, there is no uncertainty and Secretary Clinton has clearly won the most national and state delegates. Statistically, there is no outstanding information that could change the results and no way that Senator Sanders can overcome Secretary Clinton's advantage."

The head of the Iowa Democratic Party, Dr. Andy McGuire, also released a statement about the caucus results.

“Tonight we saw an historically close Iowa Democratic Caucus that featured one of our strongest turnouts ever and passion and energy from Democrats all across our state. After a year where Iowans took the time to see candidates, ask them thoughtful questions, and became volunteers and leaders themselves, tonight 171,109 Iowa Democrats came together with their neighbors to engage in a spirited discussion on the future of our country. We saw passionate, engaged Iowans turn out in all 99 counties, and for the first time ever, the IDP ran both a Tele-Caucus and satellite caucus locations, fulfilling our promise to expand participation and improve on an already incredible process."
