Technically, this could be considered frontloading because of the shift forward on the calendar, but it misses the other key element to the frontloading phenomenon that has occurred in the post-McGovern-Fraser reform era. There is a move ahead on the calendar, but there is no addition to the compression at the beginning of the process. The intent here also is not to carve out a particularly advantageous position on the calendar. Idaho would go from sharing a date with Arkansas, Kentucky and Washington to sharing a date with Nebraska and Oregon. And if history is any guide, both of those dates will likely fall after the point at which the two parties' nominees have been decided. [Yes, there are exceptions to this recent history.]
