Not only did Bush Jr start a war on false pretenses that cost $2 Trillion, he also signed the
American Dream Downpayment Act that allowed low income Americans to buy homes with little or no money down. It caused the housing bubble, mortgage crisis and the 2008 recession. When Bush Jr. entered the White House, the National Debt was $3 Trillion. When he left, it was $10 Trillion. He more than tripled the debt.
Bush Jr. was one of the most free-spending, fiscally-irresponsible president in history. It's already in the history books and all the right wing bullshit can't change that.
