From your list, I’d take “Some experts”, because I believe in science. Experts will need to measure what is in someone’s head, rather than how they look or dress, or what their name is. Hence, the original idea of “the test”.
So, purely for reference, these are the kinds of questions I, not-an-expert, had in mind for the test:
True or false: The Supreme Court chooses the Speaker of the Senate.
True or false: The House of Representatives appoints the federal court judges.
True or false: The president appoints Supreme Court judges.
True or false: The First Amendment empowers the President to declare martial law.
The Republican party’s VP candidate in 2016 was: Jeb Bush; Mike Pence; Bernie Sanders
The US Senate is a part of which branch of government: Executive or Legislative or Judicial or Politics
True or false: The speaker of the House is appointed by the Catholic Church
The number of political parties in the US: two / three / four or more
The US Constitution starts with the words: We the People / Once upon a time / I pledge allegiance
The US civil war was fought by: Patriots and Redskins / Celtics and Texans / The Union and the Confederate States
The US capital is: Mt Washington B.C., Washington DC, Washington PA
Those questions are hopefully not biased against any particular group.
Some bad questions:
True or false: Christianity is the only valid religion
True or false: Canada is the best country in the world
True of false: It is OK to punch fascists
The 2017 Adult Video News award winner in the Female Performer of the Year category was: Monica Lewinsky or Adriana Chechik or Ann Coulter
The first few are an opinion, and the last one is fringe / sub-cultural / not common knowledge, even though the answer is obvious to most by method of elimination.
This is a great and noble idea in theory. In practice, it depends on the participants being largely informed, engaged, non-selfish, and be able to see through the bullshit that the politicians serve during the campaign. And that just does not happen, yet.
Label me elitist, but I don’t think it is right that someone with a PhD in rocket science has the same vote as some of the morons featured on Jerry Springer or Dr Phil. Because they invoke images of President Camacho.
(no, I don’t have a PhD in rocket science, and Dr Phil does not return my calls).
