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 Republicans have held the governor’s mansion and state legislature since 1999, and occasionally debated whether to return to winner-take-all. Earlier this year, before the regular legislative session ended, conservative activists led by Turning Point Action urged the party to act, and Trump himself endorsed the idea.
