The Democratic Party's 2020 presidential primary process is warming up, with the New York Times reporting on the exploratory activities of Senators Elizabeth Warren, Cory Booker, Kamala Harris and Bernie Sanders, as well as former Vice President Joseph R. Biden Jr.
Ms. Warren, 69, now leads a small advance guard of Democrats who appear to be moving deliberately toward challenging President Trump. Former Vice President Joseph R. Biden Jr., wielding a political network cultivated over decades, has been reasserting himself as a party leader, while Senators Cory Booker of New Jersey and Kamala Harris of California have emerged as fresher-faced messengers for the midterms. And Senator Bernie Sanders of Vermont, the runner-up in the 2016 primaries, has been acting like a candidate as he considers another race.
All five have been traveling the country, raising money for Democrats and gauging the appeal of their personalities and favorite themes. As a group, they are a strikingly heterogeneous array of rivals for Mr. Trump, embodying the Democratic Party’s options for defining itself: They are distinguished by gender and race, span three decades in age and traverse the ideological and tonal spectrum between combative Democratic socialism and consensus-minded incrementalism.
