Let's have that debate

The Great Lie:

"If John McCain wants to have a debate about who has the judgment and temperament to be commander in chief, that is a debate I welcome," Obama said in last night's speech. This was meant to be a defense of his foreign-policy abilities, but it is actually an amusingly counter-factual statement about the man's life and political career. What sort of judgment has Obama shown in his political endorsements? How about his choice of friends, which one might charitably describe as "interesting?"

By what criteria does a man choose his friends and end up with the likes of Tony Rezko, Jeremiah Wright, and William Ayers? How does he choose his political advisors and end up with advocates of reparations for slavery, fans of Hugo Chavez, and two individuals who have been forced to resign over their alleged connections to Hamas?
