Sorry bub, but if President Bush even once thought, "Her religious beliefs, by only the virtue of their existence, are positively influencing my decision to nominate her" then he subjected her to a de facto religious test and this nomination should die in committee. A strict constructionist who read the constitution literally would argue that she's not taken any test regarding her religious beliefs or understanding. If you say she has, then produce the test..... :)
And who said I was a strict constructionist? :)
I think you are overliterally reading the passage and making it uselessly narrow to mean much of anything. "Test" has more than the single popular meaning (e.g. a written test) people think of -- check out
