After a highly contested presidential race, most major news outlets projected on November 7 that former Vice President Joe Biden had enough electoral votes to become the 46th president of the United States.

The 2020 election was unlike any other in U.S. history. About 160 million Americans voted—more than in any previous contest, according to estimates by the U.S. Elections Project. That figure represents about 66 percent of the voting-eligible population. 

The vote also made history in another important way: Biden’s running mate, U.S. Senator Kamala Harris, will become the country’s first female vice president—as well as the first Black American and the first South Asian American to hold that position. 

When the duo (pictured above) take office on January 20, they’ll face enormous challenges, including tackling the Covid-19 pandemic, improving the weakened economy, and trying to unite a deeply divided nation.
