"The scary thing is, Obama is starting to make Nixon look like a straight arrow!"
Actually, there is no comparison between the two as far as being a president. Aside from all the questionable morality of the Watergate and associated things, Nixon was one of the better (and in many ways, more liberal) presidents this country has ever had, while obama is predictably far and away the worst president we have ever had, making even jimmy carter look a little better.
Of course "aside from all the questionable morality...." is kind of like "other than that, Mrs Lincoln, how did you enjoy the play??"
Thinking on it a bit more, I would place Nixon's "morality" at no worse than clinton (another successful president in many ways), and far above obama, who makes clinton look like a truth truthful person.
