One of my friends is a mechanic and also a life-long Republican. He posts to Facebook several times a day, so the last few months have given me a fascinating view into his thoughts.
At the beginning of the war, he laughed because he had a customer ask if they should stock up on motor oil to avoid price increases. His post was really dismissive - calling the customer a nut job for being concerned about the price of oil.
A few weeks later, he made a post asking other mechanics for advice. He'd noticed that oil prices shot up, but he was still sitting on some oil he'd purchased previously. He asked if he should keep his oil change prices low, or if he should raise his prices to prepare for when he had to buy oil next.
His recent posts have been about leaving MAGA. So maybe there is some hope for him yet? However, he still doesn't seem to be leaving the Republican party. Just maybe realizing the Trump is not his lord and savior. I suspect in a couple more years, there will be no one left that claims to have lived Trump. Kind of like how Republicans now denounce George Dubya, even though they were all in at the time.
