Phil:
I expect that this training/testing/proficiency requirement will bite the dust, via SCOTUS. The issue of education/testing/proficiency has been shot down, in Katzenbach v. Morgan (384 U.S. 641 [1966]), when mostly Southern states tried to require passing a written test, to vote, as a way of eliminating those whom they didn't want to vote. The standard, for any one Constitutionally-protected right, is the same, for all of them.
