Democracy is a pack of wolves voting on which sheep to have for dinner.
Now, what I'd like to see is each person's vote multiplied by the amount he pays in taxes (all taxes: property, sales, income &c.). That would be fair, and it'd give an incentive to pay up too.
Fair point, but it seems relevant to acknowledge that the American campaign finance system as presently organized is exactly isomorphic to the "selling political power" you mention above.
