Caren, as always, an excellent piece. Well researched and superb analysis. Historically, a sitting VP tends to have an advantage when running for president. Kamala Harris will have that advantage. However, if she does not learn from her mistakes during her 2020 primary campaign -- and there were a lot of them -- she will quickly fritter away that advantage. Forecasting eventual candidates has about accuracy as a coin flip. I'm old enough to remember that no one heard of Jimmy Carter or Bill Clinton outside their respective states before they secured their party's nomination.
