That’s factually false. Nobody who matters in any meaningful way wants to “destroy” Northam. He needs to resign as governor because he can’t effectively govern a diverse state after this. But nobody is saying he can’t continue to be a physician or to do other public service.
Right, Northam's fellow Democrats will inevitably take their cue from how it's playing among their supporters, particularly being informed by social media, which is where you can find the overblown reaction.
