Are you insane? Jimmy Stewart was known as a diehard supporter of the Republican Part, and actively campaigned for Nixon and Reagan. He was was friends with Henry Fonda and Jack Lemmon, who were to the left of him politically, but they weren’t communists.
Yeah, he sure looked like one.
I guess that's why he was such a great actor. :)
If I’m not mistaken, Duke Wayne was friends with Henry Fonda.
