Yes, under my plan most counties would have a fraction of an electoral vote and each county in each state would have an equal fraction of an electoral vote.
Take Texas for example, the state has 254 counties, but an increasing number of people, mostly liberal live in Harris, Dallas, Travis, El Paso and Bexar counties. These liberal city people may one day control the votes in the state in a manner that would disenfranchise rural voters in less populated counties.
In order to equalize the voice of voters in rural counties, smaller counties would have the same power as liberal big city counties.
In other words, the voters of Loving County, Texas would have the same voting power as Harris county Texas.
Electors are people, my friend.
To allow for a fractional proportional method, would need a constitutional amendment to abolish the Electoral College, and could be stopped by states with as little as 3% of the U.S. population.
Without an amendment, the office of presidential elector remains. A presidential elector is a person, and a persons vote cannot be divided into fractions. Each state would have to use a whole-number proportional approach.
