On Nov. 3, 2020, Americans may elect their 46th president. As we pass the midway point of president Donald J. Trump’s term in office, it is time to start investigating and checking out the official candidates who have entered the race.

The Democrats, so far, dominate the arena with fifteen notable elected officials; the Republicans are represented by only two candidates, William F. Weld and Donald J. Trump.

Let’s take a look at some of the big names making headlines:

Bernie Sanders, 77, is among the more well-known candidates, given his continued presence in the public eye. After serving as a US Representative for sixteen years, Sanders was elected to the US Senate in 2006, where he is currently serving his second term after winning reelection in 2012. In the 2016 presidential campaign, Sanders gained immense popularity, but ultimately lost the Democratic Party’s nomination to Hillary Clinton. The independent senator from Vermont advocates for policies such as Medicare for all, a $15 minimum wage, and free public college.

Elizabeth Warren, 69, is a politician, law graduate, and scholar serving in the US Senate since 2013. Warren is also an adviser to the National Bankruptcy Review Commission in the 1990s. In 2010, U.S President Barack Obama appointed Warren as assistant to the president and special adviser to the Treasury secretary in order to launch the new Consumer Financial Protection Bureau. However, he later declined to nominate Warren as permanent director of the Bureau in response to retaliation from both parties. Warren’s 2020 platform focuses on breaking up big banks and protecting middle-class values by challenging corporations.

John Hickenlooper, 67, is a businessman and Democratic politician who was elected mayor of Denver in 2003 and later as the Governor of Colorado from 2011 to 2019. Over recent years, Hickenlooper has reduced the size of city government and introduced programs to help the homeless. Hickenlooper hopes to tackle climate change, provide more economic opportunities, and rectify the nation’s divided politics.

Andrew Yang, 44, is an entrepreneur and businessman who studied economics and political science at Brown, and attended law school at Columbia. Yang warns America about the threat of artificial intelligence replacing human labor. With many being at risk of unemployment in the near future, Yang proposes (along with Medicare for all) a Universal Basic Income policy for every American adult over the age of 18. The policy grants $1,000 a month paid for by a new tax on the companies benefiting most from automation. Yang hopes to create jobs for Americans in the midst of accelerated technological advancement and provide security for those in need under “Human Capitalism.”

Other officially elected Democrats who are running against Trump’s reelection are Cory Booker, Pete Buttigieg, Julian Castro, John Delaney, Tulsi Gabbard, Kirsten Gillibrand, Kamala Harris, Jay Inslee, Amy Klobuchar, Wayne Messam, Beto O’Rourke, and Marianne Williamson.

William Weld, 73, is the first Republican to announce he will challenge the president for the Republican Party’s 2020 nomination. Weld, a Harvard and Oxford graduate, is the former governor of Massachusetts. Weld ran for vice president in 2016 on the Libertarian Party ticket, but lost to Mike Pence. Weld prioritizes the individual rights of Americans and advocates for a smaller government with lower tax rates.

The presidential candidate pool holds a diverse group of returning players and new faces. The innovative and polarizing ideologies are something to look forward to in upcoming debates.
