The purpose of the direct primary, in so far as its purpose can be formulated in general terms, was to realize within the party organization, and especially in the process of nomination, accepted principles of democratic control. It is a commonplace, however, that political machinery must in the long run be judged not by its theoretical democracy but by its practical results. In a study of direct nominations, then, it appears most fruitful to examine the system in its operation rather than in its theory, and, whenever possible, to compare its working with that of the system which it supplanted.
Since 1901 the Michigan legislature has passed more than thirty acts, original and amendatory, relating to the nominating machinery. From 1901 to 1905 legislation applied to selected counties, cities, and districts; from 1905 to 1909 it was both local and general but optional with the parties and with the localities; since 1909 it has been general and mandatory. On the whole it has been halting, half-hearted, opportunistic, and unscientific, and is still far from perfection. At the present time all state officials elected in the spring, including judges of the supreme court and regents of the university, all elective state administrative officers except governor and lieutenant-governor, and all township and village officers are still nominated by the old method, a method which is also retained for the selection of delegates to state and national conventions and in a modified form for the drafting of party platforms.
