 A "Super PAC" group called The Concerned Taxpayers of America paid $150,000 for ads attacking Kratovil, and $300,000 for ads attacking Peter DeFazio of Oregon.Mid-October 2010 quarterly FEC filings showed that the group was solely funded by $300,000 from Daniel G. Schuster Inc., a concrete firm in Owings Mills, Maryland, and $200,000 from New York hedge fund executive Robert Mercer, the co-head of Renaissance Technologies of Setauket, New York.According to Dan Eggen at "The Washington Post", the group said "it was formed in September 'to engage citizens from every walk of life and political affiliation' in the fight against 'runaway spending.'"
