Is this the most effective political ad of 2016?

US Senate candidate Jason Kander was consistently trailing incumbent Roy Blunt in the Missouri race until this month. Many attribute the shift to a simple and memorable ad in response to criticism of Kander's position on gun background checks.

Bonus video: this ad by Missouri gubernatorial candidate Eric Greitens probably plays well with core supporters, but is pretty ham-fisted in comparison to Kander's.

Fun fact: 3% of Americans own about half of America's guns, "between 8 and 140 guns apiece, 17 on average."
