Morning Briefing: March 29, 2012

Even Newt Gingrich’s largest benefactor, casino billionaire Sheldon Adelson, who has given the super PAC backing Gingrich $16 million, says the former speaker is “at the end of his line.”

Gingrich reportedly had a secret meeting with Mitt Romney on Saturday, but claims the two reached “no agreement of any kind.”

Mitt Romney told a “humorous story” yesterday about how his dad, then the head of American Motors, shutdown an auto plant and moved it to Wisconsin, which made things uncomfortable when the senior Romney ran for governor in Michigan.

Mitt Romney’s dog Seamus, who was once transported in a kennel attached to the roof of the Romney family car, is getting his own SuperPAC. Democratic Operative Bob McDevitt filed paperwork to create the Animal Lovers Against Romney SuperPAC, which will have an initial budget of $1 million to blanket 10 battleground states with internet ads.

Fury over Rush Limbaugh’s sexist tirade against Sandra Fluke is dying down. Many advertisers will resume running ads on Limbaugh’s show, and there are no signs of more radio or advertiser pullouts, the Washington Post reports.

Stalemate after political stalemate has proved unhelpful for the big businesses that hoped backing Republicans in the 2010 election would reward them with tax breaks and deregulation.

Rep. Emanuel Cleaver (D-MO) plans to deliver a note to Speaker John Boehner (R-OH) today calling on him to more strictly enforce the dress code in the House chambers, following what Cleaver says was the singling out yesterday of fellow Rep. Bobby Rush (D-IL), who was kicked out of the chamber for wearing a hoodie in a show of solidarity for Trayvon Martin.

More than 30 Democrats called on President Obama to recess-appoint five Federal Election Commission (FEC) commissioners during the Easter recess next week. Chief deputy whip Peter Welch (D-VT), who wrote the Democrats’ letter, asked Obama to “use his constitutional authority” to replace the commissioners

Since Sen. Scott Brown (R-MA) and Democrat Elizabeth Warren agreed to ban outside spending in their Senate campaign, Brown has paid two penalties for outside groups that ran ads supporting him, a fairly good track record for a novel arrangement that could be a model for other races. This week, Brown agreed to pay a penalty for ads run by the American Petroleum Institute.

And finally: Law & Order star Christopher Meloni will stop at nothing to stop war lord Joseph Kony, despite his agent’s best efforts to convince him he’s in over his head in a new Funny or Die video from the Enough Project.
