It was the right decision in that he was guilty and was found as such. In that sense, I’m pleased justice worked.
However, it changes nothing about his presidential prospects unfortunately. He will not go to jail due to logistics, the worst will be house arrest and a monetary fine. It will rally his base, he’s more likely to win the election now. Hitler was also a convicted criminal (I’m not comparing to two politically, there’s just a lot of parallels in terms of blind following etc), he was still elected.
Trumps desperation to be president again was nothing to do with this court case, there’s a few more coming down the track that are federal, all of which would mean jail time. He needs to be president so he can squash them. This case was the weakest of the lot, so what this does mean is his fear of the stronger cases will now be higher.
Unfortunately, part of me believes it’s better that Trump is president for the next 4 years because that then removes the question of him ever becoming president again after that. His age means he’s unlikely to serve the full 4 year term, as is Biden. I think though if he doesn’t win, he continues to divide America until the day he dies as long as the question of him running again is still on the table. I worry if he loses again, this continues.
