You mean, he would expect to be rewarded for showing up at an event of a political ally and offering nothing but his good word? I think there's a word for that.
Trump.
I believe Grisham, because there's nothing to gain here. She's not trying to get back into Trump's good graces and, from the sounds of things, would refuse even if offered. I don't think the GOP hates her, even if the Party of Trump does, so this statement actually goes against her future interests.
Graham had a breakthrough case and said it would have been a lot worse if he wasn't vaccinated, so no, he hasn't been. But yes, he went from 2016 "we should kick Trump out of the party" to the 2020 "whatever Trump wants, he gets" with everyone else. He chose to be part of this, he chose to be on the side of Trump. Therefore, he chose to take the consequences of his actions.
For the record, as that article states, Graham said "you ought to think about it" for which he was immediately booed. Trump supporters do not even want to think about it. That's how far gone they are.

Similiar to a case or two we've heard in the past (cough elections cough) SCOTUS refuses to hear cases about Wall funding on the grounds that Biden isn't building it anymore. There's more details than that, such as people now effectively suing Biden for Trump's damages, but yet another Trump "accomplishment" is falling apart. Literally, in some places.
Also, Trump is starting to have donors come out against him, basically admitting in public that Trump wasn't worth the money the first time.
"But Breccia! Surely Trump doesn't need donations, he can fund his own campaign, just like he said he would in 2016! And also, just like he said in 2020!"
Did he, either time?
"I mean, he leant himself money at prime plus something percent, then collected from other people's donations..."
That sounds like a "no". Trump is likely building up a war chest, whether he runs in 2024 or not. He likely knows he's still got some popularity left, before the eviction notice hits Trump Tower (soon to be named Deutche Wunderbank), the cuffs click closed around his tiny wrists, or more people come to the Graham 2016 consensus that Trump is more harm than good, and look elsewhere. Like any of the dozen GOP governors who blocked mask mandates to protect the freedumbs of what's left of their population.
