Article II, Sec I, Clause 2

Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector.

Tom,

It would benefit us all if Justices were scholarly accomplished in the predominant language of our nation.  It appears to me the Roberts Court had no business sticking their noses into what is clearly a matter owned solely by state legislatures.  It doesn't surprise me, however; for 200+ years they've been twisting themselves in knots deciphering what was meant by 'may' and 'shall.'  I think the default is to assume the first use applies to those that follow.  That is to say, in the above clause, 'may' defaults to 'shall.' 

Don't take me too seriously, Tom.   We're all hunkered-down and having fun when and where we can.  

Bob
