I think the cult will carry a torch for Trump, and Vance - as Trump’s “chosen” successor - can be coached by the HF (likely already has been) to rally the troops effectively enough to achieve their goals. I agree Vance is likely to fuck something up enough eventually to turn the base off, but not right away - and that’s possibly just enough time to do a lot more damage.

Don’t get me wrong - I hope I’m wrong and you’re right - but I just can’t be sure, and so am hoping for the best while planning for the worst.
