No. We're not talking about '80s hair. 

Watch footage of any Republican convention, debate, or political forum from the last fifteen years, and you'll notice one name that gets dropped more often than any other: Ronald Reagan. Not only was the 40th president of the U.S. reasonably popular for most of his presidency, but his retrospective approval rating trends even higher. In other words, people looking back on his presidency today tend to view him more favorably than the 63% approval rating he had when he left office.
