In the midst of the turmoil of the Presidential campaign of 2020, the reality is that Democrats have lost the White vote in every election for the past 40 years, except Bill Clinton in 1996.
IF Democrats gain about 40 percent of the total white vote, mostly from suburban women, college educated men and women, and socially aware whites of both genders, they can win this next election, if the following caveats occur:
Voter Suppression, Gerrymandering, and Russian collusion is able to be controlled, where it does not undermine the will of voters.
African Americans, Latino and Hispanic Americans, Asian Americans, and younger voters of both genders turn out to vote in larger numbers than they did in 2016, as compared to 2008 and 2012.
If disappointed far left Progressives of the Bernie Sanders variety agree to overcome their resentment, and come out and vote for a likely moderate progressive candidacy, then victory over Donald Trump is insured.
Of course, having a woman, a minority person, or a gay candidate on the ticket for Vice President would help, meaning Amy Klobuchar, Kamala Harris, Cory Booker, Julian Castro, or Pete Buttigieg as the running mate, if not the nominee in any of these cases.
