DENVER – Monday is the last day for voters in Colorado to affiliate ahead of the precinct caucuses. The Colorado Secretary of State says voters must be affiliated to participate.

Both Democrats and Republicans will caucus on March 6. The caucuses, described as neighborhood meetings, are the first step to nominate candidates for the 2018 election.

“This is really a crucial step in our democratic process,” Colorado Secretary of State Wayne Williams said.

Williams stated, “In past years, more than 90 percent of candidates on the primary ballot were chosen through the caucus route.”

It was noted that although unaffiliated voters may now participate in the primary election without declaring to be a Republican or Democrat, they cannot participate in caucuses unless they register with the party 60 days in advance.
