The indictments didn't fail, he was convicted on 34 felony counts and is awaiting sentencing.
The remaining indictments are still running, not failing and more evidence is about to be unleashed into the public domain about Trump's role in Jan 6. This will be released before the election in the evidentiary hearing to be held in the Washington D.C case by Judge Chutkin.
A lot of his legal troubles pre date running for president. He's narrowly escaped jail many times since the 80s. This time it's catching up to him.
Trump's screwed and is going down fast. He doesn't need a shadowy organisation to do it, he's perfectly capable of being a felon all by himself.
Also more sexual assault victims are coming forward.
