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.

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.

A single Republican state senator appears to be holding back a push by Donald J. Trump to net a potentially pivotal electoral vote even before ballots are cast.
