I agree. It's very possible there is significant fraud in those two cities.
However, in my lifetime, Republicans have been claiming voter fraud since Nixon-Kennedy in 1960.
And what serious, or sincere, efforts have Republicans made to stop voter fraud since 1960?
Almost none - unless you count Voter ID, or updating voter rolls, which might stop some fraudulent voting, but depends entirely on local enforcement.
My blunt opinion - if the GOP loses because of fraud, we deserve to lose, because our efforts to stop it are completely pitiful.
I don’t disagree with you. Complaining about losing due to fraud you could have prevented is like a football team complaining about losing because of penalties.
