Just to clarify, Reagan became a Republican and a conservative long before he became governor of California. You really should read his autobiography. The first Republican Reagan supported for president was Eisenhower, and he campaigned for Nixon against Kennedy, even though he was still registered as a Democrat. He registered as a Republican after the 1960 election.
LOL By today’s standards JFK was a conservative.
“Ask not what your country can do for you but what YOU can do for your country.”
Imagine a politician saying that today!
