I honestly don't think there's anything Trump could do to lose the support of his MAGA base. There have been so many times when I've said "surely they'll see what he is now" only to be mistaken. It's truly a cult.
Trump and MAGA people are really 'till death do us part.....
The people that suffered the most from the first Trump administration are the white republicans: they died because they did not want to be vaccinated against COVID nor wear masks. In 2024 white republicans voted for Trump even though they were personally hurt by Trump's COVID advice.
One of my friends is a Trump supporter who almost died of COVID (he got intubated!!). His wife also got COVID. Never you mind: both of them voted for Trump in 2024.
Right, short of his actions resulting in them being fired, losing medicare or other direct impact, there is no way they will change course, they are too deep in to the grift.
That assumes that Trump, Musk and the right wing media won't spin that as Biden's fault, and that Trump is "working on something better". They will, and they will believe him.
