Bragg has a number of problems, not that he cares. His goal is to drag this out and loom over the primary process, so mission accomplished.
First, it kinda sorta is about federal campaign finance law. The statute of limitations on Trump’s “crimes” is 2 years if misdemeanors, five years if felonies. You’ll kindly note these alleged infractions took place in 2015/2016. So full stop unless Bragg can link them to an underlying crime, which he failed to name in either the indictment or his press conference. We can only assume it’s federal election or campaign finance law.
So the question becomes, can Bragg turn (expired) state misdemeanors into federal (campaign finance) felonies, when the federal government has not (and in fact declined) to charge him with that same felony? It’s basically unheard of. Bragg is literally trying to charge Trump with state federal crimes. There is obviously no such thing.
I’m not defending Trump as a human, just opining on the case. It’s tenuous at best.
One other observation: the crux of the case seems to be that Trump sought to influence the election by paying Stormy hush money to keep news of their “affair” out of the news. An affair that took place in 2006. Does Bragg really think the voting public would have been swayed by this news, but they were not swayed by Trump being caught on tape just 3 weeks before the election admitting to grabbing women by the yoo-ho
