In my recollection, when you sign a voter reg card, there is standard verbiage “I declare under penalty of perjury...” that the above [claims] are true.
So perjury may be the more direct illegal act. But, you have to have enforcement of laws for laws to mean anything, and we do not have that. So, it’s a mootish point either way.
You are right. Just look at Erick Holder dismissing a guilty verdict against racist black panthers who were physically threatening voters with billy clubs.
But wait, maybe there is hope. After, all, the DOJ recently filed a lawsuit against a school who declined to allow a muslim teacher to take time off to visit mecca.
