Just install Ted Cruz.
He KNOWS the Constitution.
If you think you have policy differences with him:
1) Check your reasoning,
2) Know that will still have the House and Senate modulating him.
that’s not a bad test. We want physicals and grades but it would probably be more worthwhile to track references to the Constitution and the Founders in the candidates collected speeches and articles. BTW, Paul Kengor applied this test to the presidents since Kennedy and guess who got the highest grade.
