"I believe it will be Crazy Bernie Sanders vs. Sleepy Joe Biden as the two finalists to run against maybe the best Economy in the history of our Country (and MANY other great things)! I look forward to facing whoever it may be. May God Rest Their Soul!" Trump said on Twitter.
Biden served as vice president from 2009 to 2017 under former President Barack Obama. Prior to that, Biden represented the state of Delaware in the US Senate between 1973 and 2009. He ran for president of the United States in 1988 and 2008, but withdrew early from both races.
More than ten Democrats have already announced their intention to run in the 2020 presidential election, including Senators Bernie Sanders, Cory Booker, Amy Klobuchar, Elizabeth Warren and Kamala Harris.
