I don't think there *HAS* been a good president in my lifetime. Reagan presided over one of the most corrupt administrations in recent history (CF: Iran-Contra, October Surprise, hell, throw in the S&L stuff as well, I'm sure there's more if I had the time to go digging.) versus some guy who had a problem with his zipper.
I don't give Reagan any more credit for the "end" of the cold war (which was just a brief respite - it's gettin' pretty frosty these days) than I do Clinton for the boom economy. Really, there's not a whole lot the Fed can do to make an economy better - but there's a whole friggin' lot it can do to make things worse.
