Not incompetence, corruption. They have already done their cheating by inserting the ballots into the optical scanners multiple times on election night. Now it has become clear that the number of ballots is less than the counted votes. A hand recount will be in Trumps favor. Keeping the reported totals means the cheating stands but Clinton gains nothing more.
Sounds like the city districts have widespread spoiling of ballots to avoid re recounting.
This means that the Democrat run cities may be the result of sustained vote fraud for decades.
Everyone expects e.g. Detroit to go Democrat, so no one pays any attention to local elections which keep the Dems in power.
Dems get the large cities, and therefore with a couple large cities in every state, they have a fighting chance to win / keep states like IL, WI, PA, MI, NV etc. etc.
What if the poor and minorities haven’t really been voting the Dems in power in the cities nearly to the extent everyone believes? Talk about slavery . . .
