The pardon of Nixon was not only wrong, it handed the Presidency to Jimmy Carter.
Still trying to polish that turd a few decades later, Ford compounded his blunder by signing a joint letter with Carter in favor of Janet Reno's preposterous "protective immunity" argument against Secret Service testimony regarding President Clinton.
It doesn't matter that the Democrats were out for Nixon's blood, the man broke the law and obstructed justice. He should have done time, just as you or I would have.
Arguing otherwise is no more principled than Clintonistas' "it's all about sex" canard.
He also signed SALT 1, which neutered our ABM (national missile defense) program for a generation. He also helped us "engage" with China, enriching their arms race against us with trade.
