People voted for O because they thought there was something in it for themselves.
How on Earth were Zuckerman and Buffett ever confused about who Obambi was ? I suspect they were not and had their own reasons for pretending otherwise . Self made billionaires might be that stupid , but that is not the way this thousandaire is betting .
Follow the money is the only answer I can come up with as to why Buffett and Zuckerman voted for Obama. Buffett and Zuyckerman must have seen future opportunities to buy or sell something if Obama were elected president instead of McCain. Money is a big game for Buffet and Zuckerman.
