This is why we needed to pass laws at both state and federal level requiring verification procedures prior to being on a ballot, and clarifying the natural born requirements.
Failure to do so, and the courts won’t touch it, especially if it’s a minority member.
There are statutes and case law rulings in California pertaining to ballot eligibility, and Kamala’s is at this point open to question (and possibly to a complaint or a formal lawsuit).
Kamala’s strength as a candidate is her “favorite son” status in California. But her weakness is that documentation of her life also exists within California, so authorized officials can easily access records pertinent to her eligibility.
Pursuit of that process, is what could lead to a drive for legislation which would place the burden of proof of eligibility on the candidate (pro-actively), rather then citizen activists (retroactively, as has been done since 2008).
