The Iowa Democratic Caucuses are  a little different from the Republican Caucuses, and from primary voting. In the Democratic Caucuses,  you first  go to a certain corner of the room to show support for the person you want to win the Caucus. In the first round at Jordan Creek Elementary, Hillary Clinton received 117 votes, and Sanders received 84. That was  a difference of 33. There were also 14 undecided.

After, there is a 30 minute convincing period, where you try to get the undecided to come to your side. You can also try to get people from other candidates to come over to the side you support.

In round two, Clinton received, 130, and Sanders received 85. The difference was then 45.

Finally, the amount of delegates is decided by a large math problem that is set up like this: the number of supporters times the amount of delegates of that location(Which is found by population) divided by the amount of people there, which was 214. In total, Clinton received 4 delegates, and Sanders received 3.

The delegates join together and they officially vote.  They decide the real winners of the Caucus.
