If you think anyone on the campaign was being paid that handsomely you should look at our FEC reports. I took a 15% pay cut to work twice as many hours and so did all of my colleagues. The money went to where it was most needed and the proof of that is that we won the election.
My point is that a large chunk of that billion dollars went to buy TV ads, which in turn helps pay the large salaries of TV newspeople who question where the money goes.
The Obama campaign spent less, got more air time, and did it through leveraging technology to optimize their ad buys. Honestly, it should have gone into the salaries of people like Kyle Rush and the hard working dedicated technology workers for more artisinal keyboards.
