John Sununu pretty much threatened Sheldon Adelson, who is funding a pro-Newt SuperPAC running ads about Bain, with retribution (emphasis mine):

This went under the radar in the crush of primary day activity yesterday, but former New Hampshire Gov. John Sununu — who has been among Mitt Romney’s most outspoken surrogates in recent weeks — lambasted casino magnate Sheldon Adelson in an appearance on Fox News for giving $5 million to the super PAC supporting Newt Gingrich.

Referring to Adelson as “not so bright” as he led into the discussion, Sununu noted that Adelson tends to woo the financial community to invest in his projects — and that many of them are Romney backers.

“Does he think people don’t remember when you attack them and pay for the attacks in the primary? Especially when one of the parties receiving that attack is the same investment community that he likes to go to to finance his expansions,” Sununu railed. “There’s just no common sense in this process, and you kind of feel sorry for people that aren’t that bright.”

The message is clear.  Anyone who attacks Romney on Bain is going to get payback from Wall Street. When that message is conveyed by the leading candidate’s spokesman and confidant, it is a lot more than a casual observation.  And if Sununu is so bold on television, you can only imagine what is going on behind the scenes from Romney supporters in the financial community.

Sounds like Adelson is feeling the pressure:

A source close to wealthy donor Sheldon Adelson, who is under fire for giving $5 million to a pro-Newt Gingrich super PAC that began running TV ads attacking Mitt Romney’s careerin private equity, distanced the Las Vegas casino magnate from the ads on Thursday.

“Some people have made this leap that Sheldon Adelson gave $5 million and every penny of that is being used to hit Mitt Romney over Bain Capital,” said the Adelson source, who asked not to be identified in order to more frankly discuss Adelson’s thinking on the subject. “Aren’t people getting in a tizzy here about something that maybe isn’t completely accurate?”

Sununu is right out of Chicago City Hall casting.
