Although losing the popular vote in 2000, George W. Bush made his mark in domestic policy with key legislation to improve public school education, subsidize prescription drugs for elderly citizens, and greatly reduce taxes for the wealthy. The tax cuts, along with spending on new crises, created the largest budget deficit in the nation’s history, and a financial crisis near the end of his presidency sent the economy into a recession.

As Islamist terrorism replaced communism as the primary threat to U.S. security, the Bush administration invaded Afghanistan in 2001 and Iraq in 2003. Bush won reelection in 2004, but stability in Iraq and Afghanistan remained elusive, and he confronted serious foreign and domestic crises in his second term. Democrats capitalized on widespread dissatisfaction with his administration to gain control of Congress in 2006 and the White House in 2008.
