What are Mid-Term Elections?
Mid-term elections are held in the United States two years after a presidential election. They are held on the first Tuesday after the first Monday in November. In these elections, all 435 seats in the House of Representatives and 33 or 34 of the 100 seats in the Senate are up for election.

Mid-term elections are important because they can serve as a referendum on the president’s performance. If the president’s party loses seats in Congress, it can make it more difficult for the president to pass his or her agenda.
History of Mid-Term Elections
Mid-term elections were first held in 1862, during the Civil War. The first mid-term elections were held in the midst of the war, and the results were seen as a referendum on President Abraham Lincoln’s handling of the war. Lincoln’s party, the Republicans, lost seats in the House of Representatives, but they retained control of the Senate.
Since 1862, mid-term elections have been held regularly, every two years. The results of mid-term elections have often been seen as a referendum on the president’s performance.
Consequences of Mid-Term Elections
The results of mid-term elections can have a significant impact on the president’s ability to govern. If the president’s party loses seats in Congress, it can make it more difficult for the president to pass his or her agenda.
For example, in 2010, the Republicans won control of the House of Representatives in the mid-term elections. This made it more difficult for President Barack Obama to pass his agenda, including his signature health care law, the Affordable Care Act.
Impact on the Economy
Mid-term elections can also have an impact on the economy. If the president’s party loses seats in Congress, it can lead to a decrease in business investment and consumer spending. This can lead to a slowdown in economic growth.
For example, in 2011, the Standard & Poor’s 500 index fell by 10% after the Republicans won control of the House of Representatives in the mid-term elections. This decline was attributed to concerns about the impact of the Republican victory on the economy.
Impact on Foreign Policy
Mid-term elections can also have an impact on foreign policy. If the president’s party loses seats in Congress, it can make it more difficult for the president to conduct foreign policy. This is because the president needs the support of Congress to pass treaties and to declare war.
For example, in 2014, the Republicans won control of the Senate in the mid-term elections. This made it more difficult for President Barack Obama to negotiate a nuclear deal with Iran. The Republicans opposed the deal, and they were able to block it in the Senate.
