College seniors are graduating into a world where unemployment may be low, but political divisiveness is high. Secretary of Education Betsy DeVos got booed at the historically black college Bethune-Cookman University and Texas Southern U. canceled a speech by Sen. John Cornyn (R-Tex.). Some students walked out on Vice President Mike Pence’s speech at Notre Dame. The President used a commencement address at the U.S. Coast Guard Academy to lambast his critics.

So did any of the scores of commencement speakers find words to help graduates (or the rest of us) navigate the minefield of politics today?

At UMass Amherst, Sen. Elizabeth Warren (D-Mass.) issued a call for greater political engagement. “I’m here to ask you to get more involved in our democracy,” she told the class of 2017. “It is no longer possible to assume that democracy will work if most Americans simply wait until election time to learn a little about the candidates and otherwise ignore what’s going on.”

Speakers called on graduates, in this era of confirmation bias, to continue to seek out new knowledge and question what they already know. “Doubt a little of your own infallibility,” former New York City Mayor Michael Bloomberg told graduates at Villanova, borrowing an expression from Benjamin Franklin.

“When I was graduating from college, I felt like I knew a lot and now that I’m about twice your age, I’m not as confident in what I know,” Sen. Corey Booker (D-N.J.) told the University of Pennsylvania. “The beautiful thing that I’ve realized is that we’re all in this struggle together.”

Humor served as a balm at what’s been the nation’s most politically charged campus this year: UC Berkeley. “Some of my immigrant friends voted for Trump because they wanted fewer taxes. They ended up with fewer relatives,” joked Iranian-American comedian Maz Jobrani to grads.

Another major theme: it’s time to pull together. “None of us can make it alone. None of us … Not even me that fought and killed predators with his bare hands,” Arnold Schwarzenegger, the former Republican governor of California, told the University of Houston.

Nice sentiments all—but nothing that went viral like 2016, when Dean James E. Ryan’s address to the Harvard Graduate School of Education got over 8.5 million views on Facebook and landed him a book deal.

This year’s viral moment? Well it won’t spawn a book—but it transcended politics. It’s comedic actor and USC alumnus Will Ferrell, reminding SoCal graduates that they can lean on one another. “If you do have a moment where you feel a little down just think of the support you have from this great Trojan family. And imagine me, literally picture my face, singing this song gently into your ear …” And then he channeled Whitney Houston and belted out “I Will Always Love You.”
