I think it would require a Constitutional Amendment.
Article II, Section 1, 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.
I don't think so.
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:
The state needs to change how the electors are chosen so that it is done more lie the electoral college, chosen by county, not popular vote.
