No, it is not -- the voting referred to in the Constitution is not ONLY for electors for president, for cryin' out loud. Your representatives to the House and your senators are FEDERAL offices, not state. This idea that is trying to be propounded that the Constitution doesn't speak to federal elections is either disingenuous or willful ignorance -- the USCon can't refer to state elections, instruct on their whys and wherefores BY DESIGN.
