Don't you hate it when you go to a concert and the singer tells you who to vote for?
One of the worst things about going to a concert this time of year is that a lot of singers like to talk about politics right in the middle of a show. This not only gets in the way of what we really came there for, the music, they have a tendency to insult half the audience who may be supporting the other candidate.
I'm perfectly okay with an artist who performs at a rally for a candidate they're supporting, but to turn their show into a commercial for a candidate in the middle of a show is simply out of place.
