The CONUS Option would restrict Round 1 to the contiguous United States, including the District of Columbia. This would reduce campaign travel expenses early in the nomination process.
The New Hampshire Option would reserve the Granite State’s “first in the nation” status. The New Hampshire primary would be held one week before the other districts (comprising the total of 8) in Round 1. Per the 2000 census allocating 2 districts to New Hampshire, the second week of Round 1 would involve the remaining 6 districts.
The One-Time No Replacement option ensures that no state would be selected for the same interval in two consecutive quadrennial cycles. This can be thought of as an insurance policy against two consecutive bad outcomes. Whatever the first throw of the dice is, your state is stuck with it; that’s your deductible. But if the second throw is the same, you’re indemnified; you get to roll again. This option also decreases the chance of two good throws in a row, reducing the possibility that a state would have a disproportional influence on two consecutive nomination races. Overall, it levels the cumulative outcomes for all states in a shorter period of time
The Swing States Option would reserve one half of the districts in each of Rounds 1 through 3 to “swing” states, where the general election is expected to be competitive. This option would give an advantage to the candidate who appeals to broadest spectrum of the electorate, better ensuring the party’s victory in the general election.
