I was in Phoenix when the Gary Hart campaign came to town, I've still got a campaign badge somewhere. He was the democratic front runner at the time. The buzz was incredible.
Then he got caught fooling around with Donna Rice. I read later that it was a setup. Dirty tricks by the GOP.
Biden was in there somewhere as well, but something happened to him? Dukakis was the eventual democratic nominee, but got walloped by Bush.
These days Trump pays off porn stars, goes around bragging about grabbing pussy, is accused of rape and assault, and get's elected President. That's progress for you.
