I'm not convinced he was left of center.
Merv Griffin is GOP and a close friend.
Heck, in the LKL transcript, Merv talks
about Johnny meeting President Reagan and
First Lady Nancy and being worried about
how they'd receive him because of the jokes
he told... naturally both Reagan's hugged him!
I think Carson was a class act.
His personal politics were kept to himself
as far as I can tell.
The Reagans were friends of many Hollywood lefties, they could see past their politics.
