So how do we nominate for president?

A:

Colorado uses a caucus process, though this year Republicans chose not to conduct a presidential preference poll at their caucuses.

And while Democratic caucuses were overwhelmed by turnout, the 127,000 who participated in the presidential straw poll at their caucuses represents less than 14% of active Democrats in the state.

Colorado is one of just 14 states that relies on caucuses in the presidential nominating process. (Alaska, Hawaii, Idaho, Iowa, Kansas, Kentucky, Maine, Minnesota, Nebraska, Nevada, North Dakota, Washington and Wyoming are the others.)
