Best VP running mate for Kamala Harris?

[Mister Mets]

Some of the people who make sense.

Beto O'Rourke- For the reasons mentioned.

Doug Jones- Another prosecutor who can double-down on various criminal reform issues. He has skill in winning elections in conservative states. He's been in Congress a short amount of time so he doesn't overshadow her, but he's an older white guy so he still seems qualified. He can be a useful campaign surrogate in Virginia, Georgia, Florida and North Carolina.

Sherrod Brown- Qualified and from the rust belt. Favorite of the progressives who might distrust a prosecutor, with appeal to centrist voters.

Chris Murphy- Younger white guy with foreign policy experience.

Seth Moulton- Younger war hero.

Ralph Northam- War hero Governor.

A Californian woman of color who married late in life probably benefits best from a running mate who is a white guy who isn't from the East Coast, isn't caricatured as stereotypically liberal, and who has a conventional family life.
