Main candidates for the 2020 presidential election

All of the nominees in the upcoming 2020 presidential election are currently full-time politicians, but they come from very different environments. The main candidates are Donald Trump and Joe Biden, representing the Republican and Democratic parties accordingly. Trump is the 45th and current president of the United States, a well-known businessman, and a real-estate developer. Biden is the former 47th vice-president of the USA alongside Barrack Obama and a lawyer by trade. The third parties I talked about previously also have their nominees - Jo Jorgensen, a psychologist and businesswoman from Illinois, running on behalf of the Libertarian party, and Howie Hawkins, former blue-collar worker.
