I have no problem with anyone standing for election to the presidency as long as they can please five-ninths of the Supreme Court.
On the other hand, the native American requirement should produce great presidents, I think: we could invite the North Koreans to the casino--the only decent thing to do. Also, alternating Inuit and Aztec presidents would certainly charm those wacky S. American democratic leftists.
On the third hand, I feel we should positively require that all Appeals and Supreme Court justices, as well as the Secretary of Defense, be thorough-going atheists: death penalties and casualties would be cast in an entirely different light if those decision-makers believed this world is all we have and all death final, and so were unable to count on God to sort 'em all out.
