Google that interview he did with Oprah Winfrey in 1988 on You Tube, and then get back to me with his changeability.
Yeah, maybe you just want to skip 1987 where he was an “expert witness” against the Reagan tax cuts, stating what a disaster they were. Then just ignore everything between 1999 and now, where he was a champion for universal healthcare, abortion, and taxes on the rich. Have a little intellectual honesty and admit this man hasn’t always been what he says he is today.
