Heinlein published "The Green Hills of Earth" in the Saturday Evening Post, February 8th, 1947 edition. Bradbury appeared in Collier's and the Post in 1950, his earliest slick publications that I can find. Furthermore, DESTINATION MOON was released a full three years before any film with Bradbury's name on it. Heinlein was just as famous as Bradbury then and now, maybe even more so.

Okay, Bradbury was a liberal then and he's a conservative now. I was mistaken. But is there any evidence that Bradbury held Alland's politics against him?
