Oh, I'm absolutely concerned about the impact of prominent Republicans signing on to this anti-democracy mess, and absolutely agree that all reasonable people need to call them out for it.
As regards the ordinary folks getting pulled along by this current, I'm very interested in questions of how to interrupt the radicalization process. Some liberals will view me as too conciliatory, undoubtedly, but I think it's important to try. This level of polarization isn't tenable. Some Trump voters are too deep into the cult, but many are not.
