Cite as: 588 U. S. ____ (2019) 15 Opinion of the Court III A In considering whether partisan gerrymandering claims are justiciable, we are mindful of Justice Kennedy’s counsel in Vieth: Any standard for resolving such claims must be grounded in a “limited and precise rationale” and be “clear, manageable, and politically neutral.” 541 U. S., at 306–308 (opinion concurring in judgment).
