Such has been the nature of the 2016 presidential elections in the United States that organisations formerly not known to pick sides have decided to endorse Hillary Clinton.

For only the third time since it was founded close to a century and a half ago, US publication The Atlantic decided to take a stand and endors Clinton. Another publication, USA Today, which too hadn't picked sides in any elections in the 34 years of its existence, said that Trump was "unfit for presidency". A bunch of Hollywood actors also got together in an advertisement directed by The Avengers maker Joss Whedon to ask people to vote for Clinton.

Bono, lead singer of Irish rock band U2 is the latest to join this list. At a concert in San Francisco, the singer began a conversation with a huge image of Trump on stage. The video of the Republican candidate had him talking about building a wall and punching people who protested against him.

“Now candidate…the only question we have for you this evening is, what is your vision for this great nation?” Bono asked the on-screen Trump who said in response, “I will build a great, great wall on the southern border of the United States.”

A few weeks ago, the rock singer had appeared on the American talk show Charlie Rose, where he said of Trump that he was "potentially the worst idea to happen to America".
