Fear is the driving factor to keep it like it is

Both sides are afraid to split electoral votes by congressional districts as battle ground states would become irrelevant. Every vote would count, the farmer and the big businessman's vote would weigh the same. Every state in my opinion should have an uneven amount of districts that would vote. The states would have a clear winner. As it stands now,a politician goes to the congressional district in a state that has the most influence and they put all their eggs in that basket to sway voters their way, the rest of the state is left holding the bag of one groups decisions. How is that a fair representation of the whole state?
