Bernie Sanders wins Colorado Democratic presidential primary; Pres. Trump wins GOP primary

DENVER -- Bernie Sanders won Colorado's Democratic presidential primary Tuesday, March 3. The state has 67 delegates at stake.

It was Colorado's first presidential primary in 20 years, and Sanders' victory showed how much the Democratic Party can attract independents, still the largest voting bloc in a state that's moved further left in recent elections.

Colorado held presidential primaries from 1992 to 2000, then dropped them to save money. In 2016, voters approved reinstating primaries after complaining about the caucus system of thousands of precinct meetings to start choosing presidential candidates.

Sanders defeated Hillary Clinton in the state's 2016 Democratic caucuses, and he has maintained an enthusiastic base in Colorado ever since.

President Donald Trump won the Republican presidential primary in Colorado.
