As stars took to social media Tuesday to encourage their followers to vote in the midterm elections, fans got a reminder that celebrities are citizens, too. While big names such as Gwen Stefani, Kid Rock and Bruce Springsteen endorsed presidential nominees in 2012, they're typically less vocal about the midterms, but that doesn't mean they weren't involved.

Complete with a cartoon portrait of herself and President Barack Obama, Kim Kardashian tweeted Monday night that she's "standing [with] Obama in the midterm election." Kardashian told the New York Daily News in 2012 that she was a Democrat.

There's been some tension in the past between Kardashian and Obama, who called her husband, Kanye West, a "jacka--" after he upstaged Taylor Swift at the 2009 Video Music Awards. In response, Kardashian told the British GQ magazine, "I don't think it's very appropriate for the president of the United States to be commenting on pop culture."

In other midterm irony, some of the public figures who appeared in Rock the Vote’s “Turn Out for What” voter outreach campaign did not vote in the 2010 midterm election. Lena Dunham, Whoopi Goldberg, Natasha Lyonne, E.J. Johnson and Darren Criss were among the people featured who did not cast ballots, The Washington Post reported. Rock the Vote spokeswoman Audrey Gelman said all participants had pledged to vote this time around.

Stars tend to vote with their wallets. Celebrities donated about $13 million to candidates during the most recent campaign cycle, Fox News reported. Big spenders included Barbra Streisand and Steven Spielberg, who both donated tens of thousands of dollars to Democratic committees. Donald Trump spent more than $100,000 on Republican organizations and candidates.

Kentucky Senate candidate Alison Lundergan Grimes received contributions from the likes of Leonardo DiCaprio, Tom Hanks and Jerry Seinfeld. New Jersey Senate candidate Cory Booker got donations from Ben Affleck, Oprah Winfrey and Matt Damon.

But maybe the most popular that way stars drummed up support was on Twitter. On Tuesday, the celebrities below as well as other famous people took a break from mundane updates and promotional messages to post about politics.
