Not a lawyer but I know for a fact you just don't go to the Supreme Court. There is a procedure and you first ask them to consider the case.
Also not a lawyer (or American), but federal elections in Canada are run by Elections Canada, a federal agency, and therefore clarification can go to the Supreme Court directly.
Elections in the US are run by the states, and therefore it has to work its way up the chain.
