The first rule of combat don't think someone doing something good for you is an ally. They can be an enemy playing the long game on you. Standing up to Disney Big whoop. Disney knows that a Governor will be out of office eventually. And they have can wait them out. Congress critters tend to be in bed with corporations to begin with. They make money off companies like Disney. Remember any decision made by a politician can be unmade by another politician.
Nope I don't trust him. You may trust him. But it would take way more than what he has done so far to trust him. My gut tells me not to trust him. And It has never been wrong when it comes to politicians.
During the election your gut also said that Trump would be able to prove the fraud well enough, and fast enough, to remain in office.
That didn't happen; the fix was in from the start.
Also, what DeSantis did too Disney is not something that can be changed back by a new governor; removing the 'special district' was something that required a vote at the state level.
DeSantis also has pissed off the Biden admin repeatedly, particularly in regards to the vax stuff (not a small thing) and generally been trying to carry on the politics of Trump without the pettiness and ego that hindered Trump realizing how many of his 'own' people were out to screw him over.
As well, this isn't combat, this is politics, and guess what, we have only 'bad options' (Trump included) anymore; DeSantis might not gut the Swamp the way Trump is threatening too, but I think DeSantis is also someone who would be more clever and subtle about his plans to fuck with the DC establishment, and has no need to be a showman about it like Trump.
Trump's actions around the vax's since the election, and since the bad side effects have become known, prove he should not be trusted to put other people before his own ego, either. Trump cares about Trump, and he will never admit fault publicly for anything that might tarnish his self-image. Plus, you forget the 'bump-stock bans' Trump endorsed, or his own endorsement of some 'Red Flag laws'; Trump was not a friend to gun owners, he just pretended to be one.
So you may not trust DeSantis, but doesn't mean Trump is trustworthy either.
