Oh, please!
Money determines the outcome of political races. The slack jawed yokels watch the slick advertising campaigns that it buys and vote accordingly, and you know it. It doesn't matter whether the money is from Soros or Koch, it still buys elections and therefore favorable treatment in the halls of Congress.
And it does no good to say, "but if people weren't so stupid, if only they wouldn't pay attention to the ads." That's like saying, "but if only people used common sense." They don't, and that's a fact of life Further, whining that "liberals do it too," while true, does nothing to address the real issue, which is the influence of money on politics.
And, until that issue is addressed, purchasing political influence will still be a good investment.
