There is a big difference between the way Soros and the Koch's spend their political money.

The lion's share of Soros' donations go to further the aims of the poor and working class. Moveon, is constantly asking me for money and specifying where it will be spent. In that way it is very democratic and transparent.

The Lions share of Koch money goes to make government friendlier to their own interests such as coal mining and lower taxes, at the expense of those with less than them.
