She might help the prosection tie together details which might simplify making the case against others but removing the criminal racketeering charge might be construed as weakness in that larger case.

Oh, I don't think so. There are different, and important, legal consequences to being convicted of a felony as opposed to misdemeanors. That was almost certainly a deal point between prosecutors and defense counsel, rather than an assessment (on either side) of the substantive strength of any specific charge. I don't think other defense counsel are likely to draw an inference about the strength of the baby RICO charges based on a plea deal.

A more plausible explanation (IMHO) is that she got a really good deal because she was the first main player (not the bail bonds guy) to cut a deal. They'll keep that door open to the other surrounding cast - the ones who weren't on the Raffensperger call - but not the main architects of the effort to change Georgia's electoral vote allocation.
