Obama's race is irrelevant, he is a very charismatic and thoughtful candidate. He seems to have the spark of greatness to him which I think is what makes this good enough to cross to hacker news. A lot of successful entrepreneurs also have great charisma.
If Obama matters to you, you'd better start thinking about his race, since it's been his obsession for decades.
Edit: and don't forget his scary church: http://www.tucc.org/about.htm . It's as bad as Romney's church was thirty years ago.
