Or you could just let Pennsylvania go first....
I was having a discussion over dinner about the problems with current presidential primary process, particularly the scheduling of them - yeah, I know, it's a controversial stance! Pretty much everybody you talk to has an idea for what could make the current scheduling better, and we were arguing the merits of various hypothetical plans when somebody observed that perhaps people with more expertise and who had actually analyzed the relevant data had looked at this question. So it was home to Wikipedia and their US Presidential Primary page, and the also good FairVote page on Presidential Primaries.
The major variations seem to involve either (1) group primaries starting with small states, and then working up to larger states towards the end of the process, (2) ordering the primaries to start with a random sampling of primaries but with structure imposed to start with "easy" primaries and work up to the larger, more expensive ones, (3) working through regions of the country in turn, or (4) pulling one state from each of a set of regions for each of a set of primary dates. FairVote has nice details on how each of these work with sample breakdowns/schedules.
The cynic in me thinks it likely, though, that any of these plans is going to lead towards a bias towards particular groups/regions and against others, and that saavy analysts will be able to work out which these are and the constituency with the best lobbying power is going to win (if anything ends up changing). To me, this calls out for a different plan (yep, despite what I said about listening to people who actually know what they are talking about, I'm going to throw in my ignorant two cents...) based on pure randomness. Let's pick a set of primary dates, and then randomly order the states among those dates. In order to prevent a state from being consistently devalued by falling late in the process, if you are in the last quarter of the primaries in one cycle, you are guaranteed to be in the first half of the primaries in the next cycle.
Sure, in any given year, you could have a bad outcome - small states could get a disproportionate say, primaries could be located such that poorer candidates have a harder time competing, etc. But you would avoid systematic biasing and considering the long-range trends of presidential elections, these concerns ought to even out. Otherwise, the debate seems to focus on whether particular goals (giving larger, urban states more say, making campaigning easier on fringe candidates, etc.) actually is desirable or not. And as I like to remind my students when looking at various AI systems, you always want to ask yourself if your highly engineered system beats random chance....
