The Freedom of Association argument makes no sense. Why is my Freedom of Association any less impacted by a supposedly neutral map where I’m “naturally” put in a district with a bunch of Democrats who I don’t agree with and vote against, instead of a Gerrymandered map where I get either the same result or (by some miracle in a state like New York) get put in a district that actually elects my Republican candidate of choice? This cannot be solved, except by proportional representation.
Because what the Constitution forbids is for the
government to single you out based on your political ideology. When your state legislature
intentionally dilutes your voting power based on your party affiliation, that is viewpoint-based discrimination in violation of your First Amendment rights.
