The President of the United States took the stage last night to support Hillary Clinton at the Democratic National Convention. As Barack Obama walked out, the audience chanted “Yes We Can,” his campaign slogan from 2008.

In his impassioned speech, POTUS commended Clinton's “unbelievable work ethic,” and brought the delegates to their feet while applauding after he said, “there has never been a man or a woman — not me, not Bill, nobody — more qualified than Hillary Clinton to serve as president of the United States of America”

But this wasn't the line that left the biggest impact, it was when Obama brought up Donald Trump and the crowed booed. “Don't boo—vote!” he said to the crowd.

In an instant, thousands of people were quoting the line on their social media accounts, including several celebrities. It left such an impression that the search interest in “voter registration” spiked +190%.

This classic line from the President goes back to his 2008 campaign but social media wasn't as influential then as it is now. With just one line, Obama was able to do what campaigns and influencers have been trying to do for years: get people to want to vote.
