Have his people check the machines. They should do everything they can. You don’t sit back without trying to mitigate the fraud. No effort leaves a much larger chance for more voter fraud.

I hope he can get some high tech people as poll watchers. Checking the machines isn’t enough. There would have to be some way to go inside the machine and check the programming within the memory cards. (And, maybe by the time election day rolls around, someone will come up with a way to do that. If anyone can find those people, Trump can.)
