Longoria was one of the president's lead surrogates in the last election, serving as a national campaign co-chairwoman and a top bundler. The "Desperate Housewives" star focused her attention on Hispanic voters, whose enrollment in the new insurance exchanges is seen as vital to ObamaCare's success. She is also on Neilson's client roster.
The nine-time Grammy winner could be a natural fit for campaigns to promote healthcare reform: he has stumped for Obama and even mentioned healthcare in his song lyrics. Legend is also a client of Neilson's.
"I think it will impact so many people," Legend said of the law in an interview last September. "Under Obamacare, as the law rolls out, so many more poor people will have access to affordable healthcare than have been able to in the past decade."
The television icon was a top Obama booster and is a close friend of Obama and his family. Though her media properties have shied away from backing healthcare reform, there is nothing stopping Winfrey from touting the law herself.
Pearl Jam guitarist Mike McCready
McCready urged voters to support Obama last October specifically because of healthcare reform. In a YouTube video, he cited his experience with Crohn's disease and said insurance companies had twice denied him coverage.
"I have a pre-existing condition, and I feel like I have some hope," McCready said, praising the law. "Anybody that doesn't have the means that I have will have it, too."
Jay-Z (and Beyoncé)
Hip-hop's power couple stood on Obama's inaugural platform in January, five years after Jay-Z first endorsed Obama for president. The pair were major fundraisers for the campaign last year, and at least one former administration official is hoping they'll join efforts to promote ObamaCare. Advertising experts, however, said not so fast — Jay-Z and Beyoncé may not be relatable enough to speak convincingly about being uninsured.
The "Scandal" actress addressed the Democratic National Convention in 2012 and said she received death threats from Republican fans following her speech.

Repealing ObamaCare would "let insurance companies go back to charging women more than men for the same care and would deny insurance to millions of Americans with preexisting conditions at the very moment when they need coverage the most," Washington wrote in an op-ed last October.
Armando "Pitbull" Perez
Perez rallied Obama supporters in Florida in the week of the 2012 election. Originally from Miami, the first-generation Cuban American was a hit when he told the crowd that the United States allows him to "control his own destiny." "Pitbull" is also close to several other high-profile Obama supporters, including Jennifer Lopez and Marc Anthony, and was reportedly part of festivities at the Democratic National Convention.
The Health and Human Services Department is in talks with the NBA to help promote ObamaCare, and nobody would be a bigger star in that effort than Miami Heat forward LeBron James. The basketball legend is receiving lots of buzz as a potential spokesman for the law who could appeal to young men.
James visited the White House in January, where he couldn't contain his excitement at meeting the president, and at one point called Obama "coach."

Judd was praised earlier this year as a rising Democratic star and an articulate supporter of progressive causes. In March, amid speculation over her political future, she gave a speech at The George Washington University about women's health issues. She's also tweeted in support of ObamaCare, joking during the election that the law covers "Romnesia."
Sarah Jessica Parker

The "Sex and the City" star raised money for Obama last year and appeared in several television interviews touting the president's record. She also appeared in the 2012 campaign's first national TV spot, airing on MTV, and worked alongside senior Obama adviser Valerie Jarrett in Ohio ahead of the election.
"The reason I care has nothing to do with me and my personal stake," Parker told Access Hollywood Live in October. "I'm simply concerned about ... access to important things like mammograms and screenings for cervical cancer."
Bonus possibilities: Bruce Springsteen, Stevie Wonder, Dave Matthews, Neil Diamond, John Mellencamp, Lady Gaga, Katy Perry, Scarlett Johansson and Marc Anthony. The California exchange's PR plan also mentioned shows like "Grey's Anatomy," "Modern Family," "The Biggest Loser" and "Dr. Oz" as possible venues for pro-ObamaCare messaging.
