No, this will be overturned, in fact when a court determines this was an illegal case, Braggs could technically be arrested for false arrest along with his stunt with timing already violating the intimidation to obstruct laws regarding Bragg obstructing the Biden investigation.
But get this: if they can find even 1 dollar he received from a foreign entity or colluding with polititians compromised by foreign pay to play, then Bragg can also be charged with election interferences and thus Treason (foreign assistance in manipulating our democracy and trying to prevent a candidate from running). It wouldn't be hard to find a politician he's been rubbing elbows with that is in China, Ukraine, or Russian pockets
