Final answer:
In 2006, George W. Bush had majorities in both the Senate and the House. However, the 2006 midterms shifted control to the Democrats, influenced by the handling of events such as Hurricane Katrina and the Iraq War.
Step-by-step explanation:
During 2006, George W. Bush enjoyed Republican majorities in both houses of Congress. This period characterized a continuation of the Republican agenda where Bush initiated major tax cuts and sought a limited government role in governance. However, events including Hurricane Katrina and growing discontent over the Iraq War undermined the administration's positions, leading to a shift in congressional control after the 2006 elections to the Democrats. It's important to note that throughout his presidency, Bush faced various challenges, such as the 9/11 attacks, which dramatically shifted his focus from a domestic agenda to initiating a global 'war on terror.' Despite a narrow victory in President Bush's previous campaign and many domestic and international interventions, the political landscape changed significantly by the mid-term elections during his second term.
