As the Obama's myriad scandals continue to expand in both severity and number, the Nixon comparison has taken root. We have an embattled White House, enemies lists, a crippled, directionless administration, and a President who seems incapable of repairing the damage done to his already weakened credibility. Unfortunately, that's where the comparison ends. Obama doesn't have Nixon's sense of dignity - so he won't resign - and he isn't faced with any legitimate threat of impeachment.
