Colorado is one of only a handful of states that still participate in a caucus system for advancing candidates to the Primary Election ballot.
The festivities get started this week, with some counties kicking things off tonight (Democrats in Denver and Jefferson counties, for example).

And Denver and JeffCo decided to hold caucuses on the same night as the State of the Union because why? I would expect even lighter attendance than usual, given the state of the world.
Republicans have some caucuses tonight, too. These dates were probably chosen before the SOTU date was known.
I know, but it'll still probably keep a lot of people away.
