Thank you for your post.
And of course, in these matters, CONGRESS is the final legal authority, not the Courts.
Congress has no interest in this issue. There hasn’t been even a minute of congressional hearing time devoted to Article II, Section 1 requirements.
The courts and state election boards are required by state statute to rule on eligibility ballot challenges. There were fifty such ballot challenges heard in 22 states plus the District of Columbia in 2012.
We are still waiting on final rulings on ballot eligibility challenges in Alabama (state Supreme Court) and Mississippi (US District Court).
