From a New York Times Editorial (January 20, 2020):
Any hope of restoring unity in the country will require modesty, a willingness to compromise and the support of the many demographics that make up the Democratic coalition — young and old, in red states and blue, black and brown and white. For Senator Klobuchar, that’s acknowledging the depth of the nation’s dysfunction. For Senator Warren, it’s understanding that the country is more diverse than her base.

…Amy Klobuchar has emerged as a standard-bearer for the Democratic center. Her vision goes beyond the incremental. Given the polarization in Washington and beyond, the best chance to enact many progressive plans could be under a Klobuchar administration.
…Elizabeth Warren has emerged as a standard-bearer for the Democratic left…Ms. Warren has proposed to pay for an expanded social safety net by imposing a new tax on wealth. But even if she could push such a bill through the Senate, the idea is constitutionally suspect and would inevitably be bogged down for years in the courts. A conservative judiciary also could constrain a President Warren’s regulatory powers, and roll back access to health care.
Ms. Klobuchar and Ms. Warren right now are the Democrats best equipped to lead that debate. May the best woman win.
