The problem with Glenn is, he started as a JFK-type Democrat, but allowed the swamp to corrupt him. The Keating Five scandal — where he was associated with another corrupt POS John McCain — only served to drag him irrevocably into the hole and compromised him forever.
My father was a very connected NASA official during the ‘60s and early ‘70s, and I got to meet John Glenn as a child. I idolized him back then, but no more.
One story I head about John Glenn when he decided to get into politics was how he decided what party to adhere to. (Glenn was old-school military publically apolitical until retirement.) The story goes as follows, he offered himself to the Ohio GOP (Rhode’s Organization) they were disinterested. Glenn then offered himself to the Ohio democrat party & the rest is history.
I have no idea if its true but I heard it from a lot of WV GOP’ers. (Friends of my father.)
