The Super PAC formerly run by Stephen Colbert, Americans for a Better Tomorrow, Tomorrow, has released its first ad to air in South Carolina this week.

Colbert announced Thursday on his show on that he would run for "President of the United States of South Carolina" and handed off control of his Super PAC to fellow comedian Jon Stewart.

The ad riffs off Romney's "corporations are people" line from this summer, saying that if Romney's record at Bain Capital is considered, then he'd be a serial killer — creatively dubbed "Mitt the Ripper" by none other than John Lithgow, the narrator.

We've reached out to the Romney campaign for comment on the ad.

The Super PAC's release is below:

Dear Super Pac Super People,

Hi again, it’s me, Jon. When I took over this Super PAC, I had no idea there’d be so much email-writing. Also, there are a lot of plants around Super PAC office with extremely specific watering schedules. Seriously, does a Northwood Spotted Fern really need to be watered "thrice fortnightly at dusk"?

Anyway, The Definitely Not Coordinated With Stephen Colbert Super PAC made an ad, and I figured you’d want to know. I’ve attached the press release below, so hopefully your mouse’s scroll-wheel isn’t broken.

Sincerely,

Jon Stewart

FOR IMMEDIATE RELEASE

The Definitely Not Coordinated With Stephen Colbert Super PAC Releases First Ad, Begins To Regret Length Of Name

AMERICA – The Definitely Not Coordinated With Stephen Colbert Super PAC released its first TV ad today, in advance of South Carolina's upcoming unnamed GOP Primary. The ad, which takes an objective look at Mitt Romney's private sector experience, is entitled "Attack In B Minor For Strings."

"Mitt Romney claims to be pro-corporations," said Jon Stewart, President of The Definitely Not Coordinated With Stephen Colbert Super PAC. "But would you let him date your daughter's corporation? Americans have been clamoring for a comprehensive study of this crucial issue, so we splurged for the full sixty-second commercial. We think South Carolinians will agree – they deserve a leader who shares their state's values, and perhaps even their state's initials."

The new spot begins airing today in a major ad buy that will blanket South Carolina from Charleston all the way to North Charleston. Those of you with some free AOL hours left can view the ad here.

The Definitely Not Coordinated With Stephen Colbert Super PAC, officially known as Americans For A Better Tomorrow, Tomorrow, is an independent, expenditure-only committee that's been proudly serving the community since late Thursday.
