effect, if possible, to every clause and word of a statute." Montclair v. Ramsdell, 107 U. S. 147, 152 (1883). In weighing this argument, it is well to remember the difference between giving a term a meaning that duplicates another part of the law, and giving a term no meaning at all. Lawmakers sometimes repeat themselves—whether out of a desire to add emphasis, a sense of belt-andsuspenders caution, or a lawyerly penchant for doublets (aid and abet, cease and desist, null and void). Lawmakers do not, however, tend to use terms that “have no operation at all." Marbury v. Madison, 1 Cranch 137, 174 (1803). So while the rule against treating a term as a redundancy is far from categorical, the rule against treating it as a nullity is as close to absolute as interpretive principles get. The Court’s reading does not merely give "by the State" a duplicative effect; it causes the phrase to have no effect whatever.
Making matters worse, the reader of the whole Act will come across a number of provisions beyond §36B that refer to the establishment of Exchanges by States. Adopting the Court’s interpretation means nullifying the term "by the State" not just once, but again and again throughout the Act. Consider for the moment only those parts of the Act that mention an "Exchange established by the State" in connection with tax credits:

- The Act directs States to screen children for eligibility for "[tax credits] under section 36B" and for "any other assistance or subsidies available for coverage obtained through" an "Exchange established by the State." 42 U. S. C. §1396w-3(b)(1)(B)-(C).
- The Act requires "an Exchange established by the
