My greatest fear for an Obama presidency is that what he will be remembered for is "first black president". He has the potential to be so much more than that.
I would have a very hard time not voting for Colin Powell. Condi I would have to consider, but it depends on where she stands on alot of issues that she really does not discuss. I will grant that few if any people in this country know more about foreign policy, and is able to articulate what she knows extremely well.
