It's obvious the amount of work involved in documenting and locating the issues is enormous and the aim is winning 270 electoral college votes.
If those states you claim had also been operating the tallying after they directed observers to go home I might believe there was some weight to your claims.
The other states were not doing exactly the same thing so your premise is faulty.

Whether you beleive fraud exists doesn't really matter to whether they should be contested.
