It was a good bit, so good - Bono decided to al gore it. Bono to virtual Trump : You're fired http://www.breitbart.com/big-hollywood/2016/10/06/bono-berates-virtual-donald-trump-concert-youre-fired/
I'm thinking of a Venn diagram. One circle has people who vote in US Presidential elections, the other is people who attend Bono concerts. The overlap between these two circles is a tiny, tiny sliver. Other than that, a concert is entertainment. Bono would have sported a Che Guevara tshirt, worn piss colored glasses, or bitten the head off a bat if it got articles written about him and sold tickets.
