The Lincoln Project took aim at Sen. Lindsey Graham (R-SC) in a new ad comparing him to a parasite.

The ad uses graphic imagery of infestation and decay to castigate the South Carolina Republican for setting aside his grave misgivings about the president to serve his political needs -- at the risk of his own Senate seat.

"Some animals are parasitic," the ad says, showing close-up images of parasitic infections. "They drink the lifeblood of their host, infect whatever they touch and spread like a virus. They're often right under our noses, camouflaged, convincing their hosts they're not harmful at all."
