Marine veteran Mark “Oz” Geist and the rest of his team were abandoned by Secretary of State Hillary Clinton in Benghazi. Geist survived. Four other Americans didn’t. Now he’s starring in a pro-Donald Trump campaign ad against Clinton.

The National Rifle Association’s political arm is launching its first ad campaign of the 2016 presidential race, with a survivor of the terror attack in Benghazi urging viewers to vote for Donald Trump. The ad, which the NRA Political Victory Fund is backing with more than $2 million, is the group’s first campaign in the presidential race and one of the larger expenditures by an outside group on behalf of the presumptive Republican nominee. The 30-second spot, entitled “Stop Clinton, Vote Trump,” features Mark Geist, a Marine Corps veteran and security contractor who fought the assault on the U.S. mission in Benghazi, Libya, in 2012 that claimed four American lives, including Ambassador Chris Stevens.

We’ll be seeing a lot of negative campaign ads going forward into November. They’re not designed to tell you “my candidate is better” so much as they are “the other candidate is worse.”

Trump’s allies are going to be spending millions in order to make that claim for him.

The media will being making the same sort of negative attacks against Trump for free.
