"I'm following the rules I wrote" doesn't make it ok whether it's Republicans limiting the number of polling stations in Democrat precincts or Democrats ballot harvesting.We get hung up too much on the word "fraud."
It's a mouthful, but "undemocratic manipulation of votes" is more accurate.
Partisans are deciding which ballots to reject, interpreting votes, "assisting" the disabled and infirm in filling out ballots, etc. Legality is irrelevant since the laws and methods enabling the abuse of procedures are partisan in nature.
Election laws, procedures, and court interpretations are still unstable the week before the election. Undemocratic manipulation of votes is happening at an industrial scale.
Democrats run the elections in Michigan and Pennsylvania. I don't see Trump winning those states.
