There are intelligent people; there are unintelligent people.  There are beautiful people; there are ugly people.  There are ambitious people; there are unambitious people.  How did they get that way?  The possibile exlanations and combinations of explanations are infinite.  All methods for measuring these charateristics are subjective.  And what is intelligence or beauty?  Are they totally subjective?  But then why is it clear to most people that Obama is intelligent and Bush is not?  We must agree on some basic qualifications, right?  

And surely we can all agree that a President should be intelligent.

Also - I test miserably.
