WHAT YOU MIGHT HAVE MISSED:

* Rep. Ron Paul (R-Texas) isn’t sure he will support the eventual GOP nominee, he told D.C.’s WMAL today. “I haven’t decided,” he said. “I want us to stand for something.” There's also still a chance he will mount a third-party bid.

* In trying to argue that her husband isn’t “stiff,” Ann Romney was a bit awkward herself. “I guess we better unzip him and let the real Mitt Romney out,” she said of the former Massachusetts governor in an interview with Baltimore’s WBAL radio.

* In an interview with ABC News’ “Nightline” airing Tuesday night, South Carolina Gov. Nikki Haley (R) said she would turn down the vice-presidential nomination if asked. “I'd say, ‘Thank you, but no,’” she explained. "I made a promise to the people of this state.”

* Federal authorities are investigating whether Arizona Attorney General Tom Horne (R) illegally coordinated with an independent expenditure group in 2010, the Arizona Capitol Times reports. A former ally of Horne’s filed the complaint.

* Tagg Romney is not pleased with AMC’s “Mad Men” for including a jab at his grandfather in Sunday’s episode. George Romney, who is governor of Michigan in the show’s current season, is called a “clown” by one of the characters. “George Romney was as good a man I've ever known. Inspirational leader, worked for civil rights, promoted freedom. We need more like him,” Mitt Romney’s eldest son said on Twitter.

WHAT YOU SHOULDN’T MISS:

* Former Alaska governor Sarah Palin will be co-hosting “Today” on NBC Tuesday morning. She’ll be on at 8 a.m. to discuss the Wisconsin primary. “What are you doing to prepare — are you reading some newspapers?” Matt Lauer joked when the appearance was announced.

* Missouri Gov. Jay Nixon (D) is one of the most popular governors in the country, but Democrats aren’t taking any chances in this increasingly conservative state. The Democratic Governors Association not only donated $500,000 to Nixon’s campaign, the DGA-funded third party group America Works USA has spent $500,000 on the race.

* New York State Sen. Adriano Espaillat is taking on Rep. Charlie Rangel in the Democratic primary. The entrenched incumbent’s district is now mostly Hispanic, and Rangel only won his last primary with 51 percent of the vote. But despite his ethics issues, Rangel has a lot of institutional support and will tough to be unseat.

* Global Strategy Group founder and president Jefrey Pollock was named “Democratic Pollster of the Year” by the American Association of Political Consultants. Pollock was involved in a number of tough races last year, helping Rep. Kathy Hochul (D-N.Y.) and West Virginia Gov. Earl Ray Tomblin (D) to victory.

* House Majority Leader Eric Cantor (R-Va.) has tapped Former Republican National Committee flack Doug Heye as his new deputy chief of staff for communications. Top Cantor spokesman Brad Dayspring quit unexpectedly about a month ago.
