There's Votes in Them Thar Hills
Share of top 0.01% of taxpayers in theUSA from The Evolution of Top Incomes: A Historical and International Perspective Piketty, Thomas; Saez, Emmanuel; American Economic Review, May 2006, v. 96, iss. 2, pp. 200
Just to be clear, I am not saying there are votes in the top 0.01 % who are getting 3% of personal income all by themselves. There are votes to be won by soaking them and spreading it out thin, and even Rham Emanuel has figured that out.
