I am not criticizing what Lupe did. That takes balls.
I am not criticizing what Obama's people did in pulling Lupe. If you booked talent to perform at YOUR party and they talked shit about you on stage, you wouldn't be very happy either.
However, it was pretty dumb of Obama's people to book Lupe if he was so vocally against Obama and his policies.
My two cents.
They pulled him after he repeatedly sang the SAME SONG for 30 minutes. If a promoter booked you, and you played the same song for 30 minutes, you'd get kicked off stage too. They said move on, or get off stage. He decided to get kicked off stage.
Just play your set, you're getting paid tons of money to be there. If you don't like Obama that's cool, either don't take the show, or put your political opinions aside and play a good show. He did neither.
