Perhaps they can show that campaign donations came from around the country and not just from New Jersey, so that people outside of New Jersey were harmed as well.

It's not too narrow, it's the way it is. This isn't made up as we go along. NJ voters aren't voting for who controls the Senate. They are voting for their Senator. No other state has a claim on who they choose.
It's not that there are no federal issues here, but equal protection is not one of them. All NJ voters will be presented with the same choices.
