Meh.
Despite all the yelling and screaming, this is basically status quo.
Presidents have always had implied immunity for official acts, and the DOJ has a policy of not prosecuting the President.
The only thing this gives Trump is the opportunity to argue that his crimes were official acts. He will argue that all the way to the Supreme Court, delaying his cases. But since Trump is going to lose, it doesn't matter if he is tried in 2025 or 2026.
