If Nixon had faults, and he certainly had some, it was his willingness to lean to the left from time to time.That he did, but I remember him affectionately.
He did love America, and the fault I see that cost him the most was his inability to think like a criminal, that's why the leftists and Marxists got over on him so easily.
A criminal or Marxist could see how the EPA could be used far beyond it's intended purpose, an honest man would read it in it's spirit.
Nixon is a mixed bag. Great on foreign policy, anti-Communist to his core. But his biggest flaw was that he thought he would be "liked" by liberals for giving them EVERYTHING they wanted domestically. EPA, quotas, affirmative action, price controls, taking us off the gold standard, the floating dollar, etc. He (Like GW Bush) thought it would win him "love" by going left on certain issues. Instead, it enraged his base. And eventually he had almost NO supporters of either party. Compare with Reagan. He didn't give a hoot about being liked by people who would never support him anyway. He just did what he thought was best for America. And he was right.
BTW, the taping system Nixon used that was so "horrible" was installed by...LBJ. And rumor has it that JFK used a similar system. Nixon knew he was a historical figure and wanted to get the transcript "correct". Stupidly it ended up costing him the Presidency. Imagine if Clinton used a similar taping system. History would NOT be kind. And Clinton knew it.
