Update: Rep. Mike Coffman’s campaign office provided a response from Douglas County Sheriff Tony Spurlock:

“Thank you, Mike Coffman for supporting the Concealed Carry Reciprocity Act! Nancy Pelosi and the liberals opposing this common sense legislation are trying to prevent Americans from protecting themselves. I appreciate you fighting for our Second Amendment rights.”

Here’s the original post:

The subject is guns but the ad campaign is partisan politics, as Everytown for Gun Safety rolls out a six-figure buy to single out Rep. Mike Coffman, the Republican from Aurora.

Because of the make-up of his district, Coffman is viewed as vulnerable every two years, and liberal donors line up to take him down.

Everytown cites Coffman’s support for the concealed carry reciprocity proposal pending in the house. H.R. 38 “amends the federal criminal code to allow a qualified individual to carry a concealed handgun into or possess a concealed handgun in another state that allows individuals to carry concealed firearms,” according to Congress.Gov.

Coffman is a co-sponsor, but so are all of Colorado’s other Republican House members, Ken Buck of Windsor, Scott Tipton of Cortez and Doug Lamborn of Colorado Springs.

Coffman’s Congressional District 6, however, is the Democrats’ best chance to pick up a seat in Colorado next year. If you’re guessing that’s a coincidence you’re probably wrong.

The House is scheduled to hear a package of gun bills this week.

“Concealed carry reciprocity would NOT create a national standard for who can carry a hidden, loaded gun in public. Instead, it would force each state to accept the concealed carry standards of every other state, even states that have weak standards, or worse, no standards at all,” Everytown spokesman said in an e-mail to Colorado Politics.

Everytown has been characterized as the left’s answer to the National Rifle Association, founded in 2014 with former New York City Mayor Michael Bloomberg’s $50 million donation and combining his two other organizations, Mayors Against Illegal Guns and Moms Demand Action for Gun Sense in America.

The Everytown campaign includes an ad in Tuesday’s Denver Post that publishes a letter from Jane Dougherty of Littleton, whose sister, Mary Sherlach, was a school psychologist killed in a mass shooting at Sandy Hook Elementary School in Connecticut five years ago this month.

Dougherty testifies for more stringent gun laws at the Colorado Capitol each year.

She writes in the letter:

Colorado has a rich tradition of hunting, responsible gun ownership, and respect for the Second Amendment. But despite the claims of the NRA, which has made the Concealed Carry Reciprocity Act of 2017 its top priority, the bill you are voting on tomorrow eviscerates our gun laws and makes it easy for people with dangerous histories, no permit and no training, to carry hidden, loaded guns in our Colorado communities.

Your colleagues have tried to hide this reckless provision inside another bill-“the Fix NICS Act”-which was introduced in the aftermath of yet another mass shooting in Sutherland Springs, Texas, where 26 more people were shot and killed less than one month ago. But make no mistake: the threat posed by the bill you are voting on tomorrow would far outweigh any benefits of the Fix NICS Act. Anyone who votes for this bill will be sacrificing public safety and undermining state gun laws across the country, including our laws here in Colorado.
