I've seen that opinion more than once and I tend to agree. Reagan conservatism has been replaced by angry populism.
Yeah, 306 Electoral College votes worth.
The alternatives were to lose gracefully AGAIN with a genteel establishment moderate Republican, or lose to an extension of Obama by Hillary Clinton.
By the way, Reagan "conservatism" included Amnesty, which only fueled illegal immigration in anticipation of future amnesties, brought by G.W. Bush, McCain etc.
Reagan wasn't a saint, either.
