Biden is running as a moderate Democrat presidential candidate, in contrast to his leftist rival Bernie Sanders. Super Tuesday results suggest that Biden, with over 40 years of political experience, will become Trump’s main adversary. Biden is popular among white workers who helped Trump win the 2016 election.

If Biden becomes the official Democratic Presidential nominee, he and Trump will compete for several East, North Central, and Midwest states. 4 years ago, Trump capitalized on the troubled economic condition of Midwest states to win the election.
