New Era Colorado hopes to harness the political power of Saturday’s March for Our Lives, a demonstration against gun violence, in Denver.

New Era is the long-established Colorado organization for politically engaged millennials from the left, and Saturday it hopes to sign up young voters beginning at 2 p.m. at the Capitol, east of the park.

“Not one more,” organizers of the Denver March said on Facebook. “We cannot allow one more child to be shot at school. We cannot allow one more teacher to make a choice to jump in front of a firing assault rifle to save the lives of students. We cannot allow one more family to wait for a call or text that never comes. Our schools are unsafe. Our children and teachers are dying. We must make it our top priority to save these lives.”

The event is one of two planned in Colorado. The other is in Boulder County. The Longmont Leads with Love March for Our Lives is at  6th Avenue and Main Street in Longmont, according to national organizers

As of Thursday, 835 events were planned across the country.

A march in Washington is expected to attract 500,000 to the nation’s Capital.

March for Our Lives is a national call for political leaders to address gun violence, as well as part of a memorial to honor the 17 students and faculty members who were killed by a gunman at Marjory Stoneman Douglas High School in Parkland, Fla., on Feb. 14.

Students convened at the state Capitol in Denver on March 14 during National Walkout Day.

“New Era Colorado is leading the call for change alongside fearless high school students across the state as the largest youth voter registration program in Colorado,” the organization said in a press advisory. “Our volunteers, staff and organizers have spread across Colorado to join students at their walkouts, marches, rallies and sit-ins – all while registering them and their peers to vote.

“This Saturday, at Colorado’s March for Our Lives in Denver, New Era volunteers will register or pre-register hundreds of young people to vote, ensuring that the energy and leadership among young Coloradans translates to power at the polls in November.”
