Reagan was successful in getting his economic recovery plan, tax reform, defense buildup and reductions in the welfare state, along with discretionary spending cuts enacted in his first term. Unlike Bush, Reagan did this with a Democrat controlled House and a tough liberal Speaker named Tip O'Neill running the show. Reagan's second term was highlighted by serious bilateral reductions in strategic nuclear weapons of both the US and the USSR. Reagan made the world a safer place for everyone. Reagan also found time to win the Cold War, dismantle the USSR, vanquish Euro-communism and free 500 million people from the once powerful totalitarian regimes of the Eastern Bloc. Reagan made pro-life issues a mainstay of his eight years as POTUS. His court nominees were for the most part highly conservative picks. Reagan signing of the Immigration Reform and Control Act of 1986 didn't turn out the way it was suppose to, but its still on the books, waiting for Bush to enforce it.
And lets not forget, Reagan's two historical landslide election victories. Not a perfect record, but a great legacy nonetheless.
