Dear Lord, people... The only thing worse than a left-winger defending Nixon is a left-winger defending Reagan.
Well he did leave the inflation, unemployment, and growth rates better than when he came in, and he managed the Soviet Union in a stellar fashion; he does not quite get credit for the Brezhnev doctrine's repeal by late 1988 but he pushed it along. Such actions went a very long way towards restoring national morale. To judge Republicans presidents as good merely because they were ineffective is not really much different from Republicans who hope the economy crashes because it will make Obama less effective.
