A bunch of his supporters who bought in to the MAGA component of the campaign are probably lower middle class ppl who lost jobs in certain industries that simply arent coming back. They vote for him because they want to have a secure, well paying job again, like what used to be more plentiful in various manufacturing. A bunch of those jobs are gone due to automation. We arent getting rid of automation.
As for the jobs that aren't, we aren't bringing auto manufacturing back, shoe manufacturing back, textiles manufacturing back, etc.
How will Don get these guys jobs?
This will hurt the enthusiasm.
If they don't get Muslims banned, don't get a wall, don't get high paying jobs back, all they are going to have left to hold tight to is that there isn't some lib in charge. Will that be enough? Nope. Don needs to do the wall and ban muslims otherwise no second term, imo.
