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.
Only States decide presidential elections, by selecting electors, and every single one of those Justices knows it.
Those first two words are doing some hard work fending off a slander suit.
