I don't think anyone just randomly shows up at the voting booth on the (guessing here) 1st Tuesday of the month in election years. I suspect virtually everyone knows about the exact date due to various forms of publicity. Especially when you consider the many different dates for many different kinds of elections.

That said, EVERY interest group is going to favor or disfavor any particular new solution due to perceived advantages of drawbacks to their cause, preventing any progress whatsoever.
