Bush's policies were deeply unpopular amongst American liberals, particularly his launching of the Iraq War which led to the return of massive protest politics in the form of opposition to the War in Iraq. Bush's approval rating went below the 50% mark in AP-Ipsos polling in December 2004. Thereafter, his approval ratings and approval of his handling of domestic and foreign policy issues steadily dropped. Bush received heavy criticism for his handling of the Iraq War, his response to Hurricane Katrina and to the Abu Ghraib prisoner abuse, NSA warrantless surveillance, the Plame affair and Guantanamo Bay detention camp controversies. Polls conducted in 2006 showed an average of 37% approval ratings for Bush which contributed to what Bush called the thumping of the Republican Party in the 2006 midterm elections.
