I'll prefer to stick with the US Constitution. No truly "real neat" conservative who was ineligible according to the Constitution would even run. And if they did, who'd want to vote for someone who demonstrated that they did not care to "preserve, protect and defend" that instrument of freedom.
You said it. A real conservative would never dream of throwing his/her hat in the ring if he/she wasn't Constitutionally qualified for the office.
