No surprise there since the 5-4 decision of the SC says:
“political questions beyond the reach of the federal courts”
Addendum:
While the US SC has just ruled that it is the states’ role in awarding electoral votes, there is controversy over the electoral vote distribution and if the population should determine the number of electoral votes or the number of citizen/voters only.

To adhere to a standard of “one person, one vote,” the Supreme Court requires each congressional district to contain a roughly equal number of people. The court has also ruled that gerrymandering legislative maps to dilute the power of racial minorities is unlawful.
The one person one vote comes up in the context of the Equal Protection Clause, which requires substantially equal legislative representation for all citizens in a State regardless of where they reside.
The most relevant Supreme Court case is Reynolds v. Sims , 377 U.S. 533 (1964)
In Evenwel v. Abbott, 578 U.S. __ (2016), the Supreme Court held that when drawing legislative districts, state legislatures may use the total population of areas within the state, rather than being restricted to using the voting-eligible populations.
