ABC News’ Jonathan Karl ( @jonkarl) reports:

An emotionally charged and slickly produced new video obtained by ABC News from the group Americans for Herman Cain portrays the sexual harassment story as a racially motivated effort to destroy Herman Cain.

The video ends with the Clarence Thomas’s closing statement at his 1991 confirmation hearing:  “This is a circus. It is a national disgrace. It is a high tech lynching for uppity blacks who in any way deign to think for themselves . It is a message that unless you kowtow to an old order you will be lynched, destroyed caricatured rather than hung from a tree.”

As Thomas speaks, the video superimposes the words “Don’t let the LEFT do it again.”

Americans for Herman Cain is a so-called Super Pac independent of his campaign.

A spokesman for the group tells ABC News the ad will run on television in Iowa next week and in a series of Internet ads on the Drudge Report and elsewhere.  It will also be emailed to 25,000 Republicans in Iowa.

Watch video of the ad.
