This is a completely non-issue... seriously. Look at how many people in every campaign that get positions within the administration including chief of staff or more... the people who raised that money are supporters and were not guaranteed anything... it's NOT pay-to-play because noone knew if he was even going to win. Pay-to-play is when you are trying to motivate someone to do something and they require contributions for that action... Obama didn't do that... he only rewarded top fund raisers with positions and I don't see anything wrong with that period. It's not the "sale" of anything... no matter what the stupid fuck in that article says... there were NO guarantees because he had to win in order for that to come to pass and there is nothing new about this practice.
Here is an article about 4 specific people Bush appointed under the same circumstances
