I have two 23 year old daughters for these 3 weeks. I think her point is that a state has election laws and the Supreme Court of that state ruled on the interpretations of those laws. Therefore, a federal interpretation was not going to be any "more correct" - state's rights and all. I guess it would be more fitting if you found in her writings some anti State's rights text.
I've heard some Liberals saying "States rights" is a dog-whistle for violating peoples rights.
