Each county should get an electoral vote. County lines are fixed and cannot be changed without 2/3 majority vote in BOTH state Houses. Fixed. Next question.
Love it. How do we proceed?
Amend your state constitution.
The Founding Fathers loathed rotten boroughs and wrote Article One, Section 2 of the Constitution to guarantee equal apportionment.
Gerrymandering is still a problem. There need to be federal laws regarding compactness, contiguousness, etc. I think color-blindness should be part of it but that's not going to happen any time soon.
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 guess it would have to be done on a state by state basis. Although perhaps a convention of states could get it done with a constitutional amendment. I don’t have a solution, just spitballing.
