IMO it’s not really the MAGA idiots you need to worry about. It’s the influential people in the republican party who are supporting Trump.

You’re right that the stereotypical trump supporter can’t be dissuaded by economic hardship.

However, the people that thought Trump was going to deliver them never before seen profits through de-regulation can very easily be dissuaded be economic hardship.

An economic hole is forming, and if it’s deep enough and wide enough Trump will be unseated.
