This is based on 43 states being considered "non-negotiable" and "set in stone" while only 7 are considered "swing" states
Also consider I specified "voters", who are at best only 2/3 of the total population, which leaves out about 100 million extra people
small candiates will never be able to win anything without campaign finance reform anyways so it would be better just to hold it on all on the same day.
Campaign finance reform is never going to happen in America why would the rich give up their legalized corruption? You wont get that til theres an actual revolution.
