“Each State shall appoint, in a manner as the Legislature thereof may direct, a number of Electors...”
It could not be more clear. If the Pennsylvania Legislature so chooses, it can appoint Electors directly. The Florida Legislature was going to do just that in 2000, yet another reason the USSC never should have heard the Bush v. Gore case.
At the general election to be held in the year 1940, and every fourth year thereafter, there shall be elected by the qualified electors of the Commonwealth, persons to be known as electors of President and Vice-President of the United States, and referred to in this act as presidential electors, equal in number to the whole number of senators and representatives to which this State may be entitled in the Congress of the United States.
