If you live in a state that holds a regular old primary blind ballot, you may be unsure of how, exactly, the Iowa Caucus functions and why it is so important.

In the grand scheme of delegates and electoral votes, Iowa is a relatively unimportant state politically. The great people of Iowa (and shortly after, New Hampshire) just happen to have the unfortunate honor of being the first state to vote in the primary election. All eyes are on their choice because it is the first chance for voters to put their official support behind a candidate after months of campaigning and donations.

Vermont Public Radio put together this video of how the Iowa Caucus works using Legos, so if you’re a little foggy on the details this video should prepare you for Monday’s events.
