Most Atrocious Political Ad Of 2014?

Think Progress wonders if this is the "most atrocious political ad of 2014."

If you want to run for office some day, you better not believe that everyone is entitled to legal counsel before the government locks them away. Or, at least, that’s the message sent by a new Republican Governors Association ad targeting Vincent Sheheen, a former prosecutor who now represents civil and criminal clients in private practice. Sheheen is a Democratic candidate for governor against incumbent Nikki Haley (R-SC). The RGA’s ad attacks Sheheen for “defend[ing] violent criminals” and ends with the tagline “Vincent Sheheen protects criminals not South Carolina.” The implication of this ad is that Sheheen is somehow unfit for public office because he once provided legal counsel to people accused of crimes.
