Ronald Reagan started out as a democrat.
There’s no comparison to Reagan. Reagan put in decades of work towards consetvatism. Reagan had a philosophical underpinning and wrote about his beliefs. Reagan did a lot. He didn’t just yell out a few phrases and make a bunch of confused dtatements.
(Also, Ronald Reagan never, ever supported socialized medicine, and was not ever in the casino biz.)
