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.

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.

Republicans are stepping up their efforts to change Nebraska's electoral vote process to winner-take-all -- a move that would benefit former President Donald Trump in an expected close November election in which a single vote could make a key difference in the Electoral College.
