I remember first hearing Tony Campolo back in the 1970’s. He made no bones about his hatred for capitalism - in his view it is anti-christian. He made outrageous statements about our history and the Founding Fathers, demonstrating that either he was completely ignorant of our history or he was just a bald faced liar.
In the context of preaching Jesus and the cross, he could sound very evangelical, but beyond that narrow topic, he was, and apparently still is, totally left wing. I lost respect for him a long time ago.
