I keep thinking that if several people post on forms like this it increases the chances of getting a positive response eventually.
Keep in mind that the federal government doesn’t have the authority to mandate a particular voting system in any region (except in DC, which I doubt they’d bother with).
That has not stopped the IRV propagandists from trying to get it passed anyway. I think it was HR 3057 in the previous congress that would have mandated IRV for all House and Senate elections. Even if it fails in the Court, that is only going to bring more unneeded attention to IRV.
