I think the headline is misleading.
It does not appear to me that the complainant is specifically challenging anyone’s eligibility at this juncture. She appears to be asking SCOTUS to define “Natural Born Citizen”, and she used those three men as examples.
IF SCOTUS does what she asks, then their eligibility, and the eligibility of everyone else, will be easily determined.
"She appears to be asking SCOTUS to define Natural Born Citizen, and she used those three men as examples."
Then it should be amended to include Obama.
According to the brief she filed she's specifically challenging Obama's eligibility for the office, and mentions that three other candidates on the horizon she believed are also ineligible as further need for the court to rule.
