This analysis and my previous analysis showing no correlation with state-level vote results does not invalidate the work done by Doug Ross, Gateway Pundit, and others on specific abuses. It does tend to support Megan McArdle's view that it's crony capitalism:
I would be less surprised to find out that the administration rescued specific donors from the hit list than to find that they deliberately closed Republican dealerships.I still think there's a strong argument that the administration (not Chrysler) did close dealerships that donated to Republicans. Doug Ross and Gateway Pundit are pursuing a more fruitful path than mine by focusing on the donor data.
