Reagan was rabidly pro-abortion as governor, and handed 3.5 million Mexicans amnesty, without doing a damn thing to secure the border (not because of Congress, because he naivelybelieved in open borders). He turned tail and ran after 241 Marines were slaughtered by Hizbollah in Beirut, when he could have strangled the Islamic Jihad baby in its crib before it became Hamas, Al Queda and ISIS. Worse, he was stupidly convinced by a photo of a Druze baby killed by the PLO (shown by Arabist James Baker) that it was Israel's fault and forced them out of Lebanon, when the PLO was about to be destroyed. He "defeated" the USSR, while doing nothing to stop the USSR's actual victory in American schools and civil service (YouTube: Yuri Besmenov to understand how). What the hell was so great about Ronald Reagan?
If Trump builds a wall, and does nothing else, put him on Mt. Rushmore.
