“Finally, the Court remarks in a footnote that the Clean Elections Commission’s website once stated that the ‘‘Act was passed by the people of Arizona . . . to level the playing field.’ Ante, at 24, n. 10. I can understand why the majority does not place much emphasis on this point.Some members of the majority have ridiculed the practice of relying on subsequent statements by legislators to demonstrate an earlier Congress’s intent in enacting a statute. See, e.g., Sullivan v. Finkelstein, 496 U. S. 617, 631–632 (1990) (SCALIA, J., concurring in part); United States v. Hayes, 555 U. S. 415, 434–435 (2009) (ROBERTS,
C. J., dissenting). Yet here the majority makes a much stranger claim: that a statement appearing on a government website in 2011 (written by who-knows-whom?) reveals what hundreds of thousands of Arizona’s voters sought to do in 1998 when they enacted the Clean Elections Act by referendum. Just to state that proposition is to know it is wrong.”
