These questions might not seem all that important until you consider the fact that President Barack Obama may owe his presidency to media mogul and talk show host Oprah Winfrey. A study published in the Journal of Law, Economics & Organization in 2013 found that Winfrey’s endorsement of Obama over Hillary Clinton in the 2008 Democratic primary gained him over a million votes—more or less the same number of votes by which he beat Clinton.

Clinton seems to have learned that lesson and this time around has secured the endorsements of a number of influential personalities. Here are just a few of the celebs rooting for Team Hillary:

Kim Kardashian & Kanye West

Kim Kardashian West posted a selfie with the Democratic frontrunner and her husband Kanye with the hashtag #HillaryforPresident.

I got my selfie!!! I really loved hearing her speak & hearing her goals for our country! #HillaryForPresident

Robert DeNiro

Back in April in an interview with the Daily Beast, actor Robert DeNiro said, “I think that [Hillary Clinton]’s paid her dues. There are going to be no surprises, and she has earned the right to be president and the head of the country at this point. It’s that simple. And she’s a woman, which is very important because her take on things may be what we need right now.”

Lena Dunham

Girls creator Lena Dunham wrote the following on Instagram in honor of Clinton’s birthday on Monday: “Dear Madame Secretary, this is a great excuse to tell you that I admire you, am inspired by you (especially this week when you took so much in your powerful stride) and, most importantly, I think you look great with an up do as well as a down do.”

It’s almost @hillaryclinton’s birthday! Dear Madame Secretary, this is a great excuse to tell you that I admire you, am inspired by you (especially this week when you took so much in your powerful stride) and, most importantly, I think you look great with an up do as well as a down do. Love, Lena 🎂

Pharrell Williams

Hip hop producer Pharrell Williams showed his support for Clinton when he told GQ back in March: “Hillary’s gonna win. Listen, I’m reaching out to her right now. She’s gonna win.”

Beyonce

In May, a fan account tweeted a photo of Beyonce with the caption: “Beyonce steps out in support of the Hillary Rodham Clinton Campaign Event.” Queen Bey was reportedly attending a Clinton fundraiser in New York City.

Magic Johnson

This past Monday, former Los Angeles Lakers point guard and basketball star Magic Johnson tweeted a happy birthday message to Clinton, saying she “has [his] vote to be the next President of the United States!”

Happy Birthday to @HillaryClinton, who has my vote to be the next President of the United States! #HBDHRC

Katy Perry

Katy Perry showed her support for Hillary by joining her on the campaign trail in swing state Iowa, as well as taking over her Instagram during the state rally. She posted a photo of the two holding hands on her own account, with a lengthy caption explaining her support.

🎂Happy Birthday🎂 to our next great leader @hillaryclinton !!! This past weekend, I was honored to be able to sit down with Maya Harris, one of HRC’s senior policy (aka plans for the future) advisors before joining the stage with Hillary the next day. I wanted to be more informed and educated on her plans and dreams for our country. I never want to be a puppet, and always want to feel my own purpose and ownership in everything I do. Maya and I, and some of my closest girlfriends, had the most incredible, eye-opening 3 hours of conversation about the future. We went over so many points and asked the hard questions on everything from gun control to birth control to health care to affordable education to a realistic approach in finding the middle class again. I was never raised with economic privilege and found money to be the main source of pain for my own family growing up, so I understand why there is a need for such change. I am still learning and educating myself on the world of politics and searching for every strand of authenticity buried deep in it. What I heard and experienced this weekend empowers me to believe that real change is possible and on the way! Ladies! There are so many incredible opportunities for us that are possible: equal pay, paid leave (you don’t lose your job if you want to have a family) and YOUR choice to have a family when and if it’s RIGHT FOR YOU! These are just some of the reasons I am standing with her and will continue to do so. Next year’s election is one of the most important ones in decades, and the choices we make will have a profound effect on women for years to come. So, I stand with her for my daughters and their daughters, and beyond what time gives me. Get informed, get involved and become empowered! Strong women help create strong families! ❤️ See link in bio for 📷 from the weekend👗 by @bcompleted

These are just a few of the celebrities endorsing Clinton; Marie Claire has a more complete roundup of Clinton endorsers as well as celebrity supporters of other candidates.

Bernie Sanders (I-VT), like Clinton, is gunning for the Democratic nomination and has received support from comedienne Sarah Silverman and actress Susan Sarandon, according to Marie Claire. Republican frontrunner Donald Trump has been endorsed by football star Tom Brady (sort of) and actress Kirstie Alley, while Ben Carson, who is catching up to Trump in the polls, received an endorsement from rocker Kid Rock, according to the same publication. Notably, neither Carly Fiorina nor Jeb Bush have received endorsements from high-profile celebrities.
