With less than a week to go until Election Day on Nov 5th, Donald Trump and Kamala Harris are holding rallies across the United States in a final push before the big day. Here are 10 interesting facts we learned about the US presidential election.

1. Election Day Origins: The US designated the first Tuesday of November as Election Day back in 1845. This timing was chosen to accommodate farmers who needed to finish their harvests. Tuesday was picked to give people enough time to travel to polling stations after the Sunday church service.

2. Presidential Requirements: According to the US Constitution, there are only three requirements to become president: a candidate must 1) be at least 35 years old, 2) have lived in the US for at least 14 years, and 3) be a natural-born citizen.

3. Stock Market vs. Elections: Research by U.S. Bank suggests that economic trends and inflation have a stronger and more consistent impact on market returns than election outcomes.

4. First Natural-Born President: Martin Van Buren, elected in 1837, was the first president born as a US citizen. All previous presidents were born as British subjects.

5. Low Voting Participation: The US often has a lower voter turnout compared to other nations. Notably, turnout was over 60% in 1964 and 1968, but many elections, especially midterms, see less than 50% participation.

6. Electoral College System: The President of the United States is not elected directly by popular vote. Instead, the Electoral College system is used, where each state's electoral votes equal its total number of Senators and Representatives in Congress. This system can sometimes lead to a candidate winning the presidency without winning the popular vote.

7. Popular Vote vs. Electoral College: Four times in history, a candidate has won the popular vote but lost the election: Andrew Jackson in 1824, Samuel Tilden in 1876, Grover Cleveland in 1888, and Al Gore in 2000.

8. Women’s Right to Vote: Women gained the right to vote in 1920, thanks to the 19th Amendment. This milestone was the result of a long and hard-fought women's suffrage movement.

9. Election Results Timing: Election results are not finalized on Election Day. Each state has its own certification deadline, ranging from 2 to 29 days after the election. Accurate and timely ballot counting is crucial to prevent misinformation during this period.

10. Voting from Space: Astronauts have been able to vote from space since 1997. Secure electronic ballots are sent to the International Space Station, where astronauts can cast their votes. The completed ballots are then sent back to Earth and delivered to the appropriate County Clerk's office. Many astronauts vote as Texas residents due to their training in Houston.
