Nebraska's split-vote electoral system, which the Democrat-leaning Maine also uses, came into effect in 1991, with the state facing multiple attempts to repeal it since. The current proposal was introduced in 2023 by Senator Loren Lippincott.

Sen. Lindsey Graham said it's "very reasonable" for Nebraska to push for a change to its electoral vote system because the election could come down to a single electoral vote.

Maine Democrats were supposed to come to her rescue. But a top state official says they likely missed their window.
