On the eve of a key vote, Moms Demand Action are demanding support for Karen McCormick in the Democratic race to face Republican incumbent U.S. Rep. Ken Buck in November.

The organization is one of the country’s best-known anti-gun violence groups. It was one of the driving forces for the March for Our Lives rallies across the country last month.

McCormick, a veterinarian from Longmont is facing a primary field that as of now includes Chase Kohne, Larry Germanson, Richard Weil and Len Sistek Jr.

To make the June 26 primary ballot any of the candidates need to get 30 percent of the delegates at Friday afternoon’s Congressional District 4 Assembly at 1st Bank Center Arena in Broomfield.

“As a mom of three, this recognition means a great deal to me,” McCormick said in a statement about the support from Moms Demand Action. “Too many Colorado families have suffered losing a loved one to gun violence. It’s long past time for Washington to do something on the federal level.”

She cited polls supporting expanded background checks.

“This isn’t a partisan issue,” McCormick stated. “But we all know that Congress isn’t going to do anything about common sense gun safety as long as we’re represented by career politicians like Ken Buck who are bought and paid for by the NRA. I will answer to the Moms and people of Colorado on this issue, not the NRA.”

Buck supports Second Amendment rights and has received campaign support from the National Rifle Association.

“Reducing and preventing gun violence is a public safety issue, not a political one,” said the national organization jumping into a local political race.

Moms said, “Responsible gun owners know that supporting the Second Amendment goes hand in hand with common sense solutions to reduce gun violence. Doing more to keep guns out of the hands of felons, domestic abusers and people with dangerous histories, knowing that respecting rights and protecting people go hand-in-hand.”

McCormick said background checks passed by Democrats in Colorado are making it harder for people with criminal histories to buy guns, including those with homicide records.

“Congress should follow Colorado’s lead,” she stated. “If elected I will work across the aisle to pass common sense gun violence prevention measures that respect the rights of law-abiding gun owners while keeping our communities safe.”
