I am not sure what an economist would say, but I also blame Bush 43. GOP-led deregulation, tax cuts, and debt-funded wars led to a gigantic overleveraged economic bubble which crashed in 1929 fashion. They were decisions that George HW Bush-style moderate conservatives balked at.
In terms of casting blame for the high unemployment rate, 26 percent of unemployed adults cited former President George W. Bush; 12 percent pointed the finger at banks; 8 percent highlighted jobs going overseas and the same number blamed politicians. Only 3 percent blamed President Obama.
