In the first instance, there were one thousand, two hundred and twelve (1,212) candidates that filed to run for the United States presidency, which includes 23 Green candidates, 65 Libertarian candidates, 164 Republican candidates, 323 Democratic candidates, and others. However, as it stands, it seems as though it is only Donald John Trump and Joe Biden that is only known to be running for the presidency. Of course, they are the favorite candidates.
Nonetheless, there were many other candidates who have dropped out of the list of the US presidential election (2020), from both the Republicans and the Democrats. The candidates from the Democrats include Bernie Sanders, Tulsi Gabbard, Elizabeth Warren, Michael R. Bloomberg, Amy Klobuchar, Pete Buttigieg, Tom Steyer, Deval Patrick, Andrew Yang, Michael Bennet, John Delaney, Cory Booker, Marianne Williamson, Julian Castro, Kamala Harris, Steve Bullock, Joe Sestak, Wayne Messam, and a few others. And from the Republicans, the dropped candidates are William F. Weld, Joe Walsh, and Mark Sanford.
