With the passage of Missouri’s constitutional carry law this week, the Senate race in the Show Me State turned to guns.

This story from says Senate contender and current Missouri Secretary of State Jason Kander (D) called out his opponent, incumbent Sen. Roy Blunt (R) for attacking him on the subject of gun rights in a video, during which he assembles an AR-15 while blindfolded.

“Well, in the Army, I learned how to use and respect my rifle,” Kander said while assembling the rifle. “In Afghanistan, I’d volunteer to be an extra gun in a convoy of unarmored SUVs and in the state legislature I supported Second Amendment rights. I also believe in background checks, so that terrorists can’t get their hands on one of these. I approved this message because I’d like to see Sen. Blunt do this.”

The ad comes after month of heated Twitter exchanges between the two candidates over this issue, the story says, including one in which Kander was questioned about his acknowledgement of radical Islam.

Kander tweeted back, saying, “I volunteered to serve in Afghanistan to fight radical Islamic terrorism. Think before you tweet.”

Kander also released a new ad on Wednesday opening with what appears to be combat footage from the Middle East.

“There are a lot of men and women serving our country overseas who never ask what’s in it for them,” Kander says. “They do their jobs in some of the toughest, hardest, most dangerous places on Earth. They get sent there by politicians, but they do it for their country and for each other. I know because I was there alongside many of them…I don’t want the sacrifices made in Iraq and Afghanistan to be forgotten in Washington, but there are far too many there who put their party, their pay raises and their political careers ahead of doing what’s right for our country.”

Blunt has not publicly responded to Kander’s latest ad, the story says.

Last week, the NRA put out its own ad against Kander, attacking his Second Amendment voting record.

“Missouri voters deserve to know that their Second Amendment freedoms hang in the balance this November,” said Chris W. Cox, chairman of the NRA Political Victory Fund, in a statement. “The next Missouri senator will help determine control of the Supreme Court. Jason Kander would be devastating for law-abiding citizens’ fundamental right of self-defense in the U.S. Senate.”

“It’s 4 a.m. and something’s not right,” a female voice says as a perpetrator breaks through the front door of a house. “You have a right to protect your home with a firearm, but liberal politician Jason Kander voted against your right. Missouri’s next senator will decide control of the Supreme Court. Jason Kander refused to defend your Second Amendment rights in Jefferson City. How could you trust him in Washington?”

Most of this comes from the fact that Kander voted against a bill in 2009, HB 668, to lower the age at which a Missourian could obtain a concealed carry permit. The bill also included a provision allowing the use of deadly force in property protection (stand your ground law) and would allow guns on college campuses. The bill passed the House and was sent to committee, the story says.

Recently, however, Kander voted to lower the state’s concealed carry age from 23 to 21 for Missourians and from 21 to 18 for military service members.
