We're going off-topic, but Obama lied about what Bush did in Iraq. He lied about the Status of Forces Agreement, first taking credit for bugging out of Iraq in 2011, and then claiming that he had no choice because had to honor Bush's agreement.
He lied about what Bush had accomplished with respect to Iran's nuclear program, blaming him for Iran acquiring centrifuge technology, even though Bush's administration through its pressure on and subsequent deal with Qaddafi was able to unravel the A Q Khan nuclear tech smuggling network (which was responsible for giving Iran centrifuge tech).
He lied about the Fast and Furious program beginning under Bush.
I could go on for pages if I bring up stuff related to the economy, the financial crisis, financial regulation, and taxes.
