What it's about

The Supreme Court held that states may enforce those pledges and punish so-called faithless electors.

The case concerns how much independence members of the Electoral College have when formally choosing a president.

Question presented

Whether enforcement of this law is unconstitutional because: (1) a State has no power to legally enforce how a presidential elector casts his or her ballot; and (2) a State penalizing an elector for exercising his or her constitutional discretion to vote violates the First Amendment.

What the Court decided

Holding

A State may enforce an elector’s pledge to support his party’s nominee—and the state voters’ choice—for President. 193 Wash. 2d 380, 441 P. 3d 807, affirmed.
