I’m not sure of the constitutionality of such a law or statute. You see, if some other state passed the same law, you’d end up with a continuous, contradictory loop, thus rendering New Hampshire’s law useless.

Apparently, it is only 7 days previous. I was mistaken. That is, however, still in 2007.
“The presidential primary election shall be held on the second Tuesday in March or on a date selected by the secretary of state which is 7 days or more immediately preceding the date on which any other state shall hold a similar election, whichever is earlier, of each year when a president of the United States is to be elected or the year previous.
