Monday is the deadline to affiliate for Coloradans who want to participate in the Republican or Democrat precinct caucuses. Voters must be affiliated to participate.
Caucuses, which are basically neighborhood meetings, are the first step in nominating candidates for the 2018 election. Both parties will caucus March 6. At the caucuses, delegates that will attend the county, legislative, congressional districts and state assemblies will be chosen.
"This is really a crucial step in our democratic process," Colorado Secretary of State Wayne Williams said.
