Since the breaking news is that there will be no recount in PA, Trump should drop his objections in MI and WI.
He is guaranteed the win with the PA result, and if he can bankrupt Jill in MI and WI we will all be better off. If they stop the recount, she gets the unspent money back in those states.
He should fight them at every turn. I don't see any reason to let Hillary get any closer.
There are no guarantees.
