If you understand what a Green Card is, the Red Card is basically a permanent Green Card. Were what you suggest even a remote possibility of being an issue, it could be done today by a Green Card holder. Assuming that hell froze over and the SC decided to take it up, it would be one of the fastest smackdowns in history. Elimination of the Green Card program (which is what would have to happen in your scenario) would eliminate the ability for the US to allow anyone to enter the country LEGALLY and apply for citizenship. Essentially, citizenship ... and therefore the Constitution, would cease to exist. Like I said, I have heard some serious dumbass strawman arguements before, but this one takes the cake.
I brought up birther as an example of something that upsets a LOT of people, that impacts our country greatly, and the SC will never ever touch it.
Finally, your example of the local elections is sad, but at each level where the D’s implement something like that, a citizen (citizen in this context would mean someone who the court would consider to have standing) has the right to challenge it in court. If those statutes still exist, I can only assume they have not been challenged. Were they challenged and found lawful, then they should have been appealed. Where are they in the appeal process? If nobody is suing, and nobody appealing, then idiocy like that can exist.
