Pennsylvania governor Josh Shapiro is perhaps the top contender to be Kamala Harris’s running mate. But Shapiro would be an awful selection, with a history of alienating and antagonizing core party constituencies and caving to pressure on major issues.
How can it be anyone other than the astronaut?
Probably because of the electoral college. There’s reason to believe she is going to choose a governor as her VP pick, which would exclude Mark Kelly.
That and if she picked Kelly, that would remove a Democrat from the Senate, and the Senate can’t afford to lose any Democrats.
