The push to change Nebraska’s electoral vote allocation is being led by GOP Gov. Jim Pillen and Sen. Lindsey Graham (R-S.C.). Graham flew to the state to lobby state lawmakers at the governor’s mansion on Wednesday.

Nebraska’s entire congressional delegation also endorsed the push in a letter on Wednesday to Pillen and John Arch, the Republican speaker of the state’s unicameral legislature.

If Nebraska changes how it allocates its electoral votes, it could have a significant impact on the outcome of the election. If Harris wins the three northern Blue Wall states of Michigan, Pennsylvania and Wisconsin and Nebraska’s 2nd Congressional District, then she wouldn’t need to win any other swing state to win the election. If, however, that one electoral vote from Nebraska instead goes to Trump, as it would in a winner-take-all allocation, Harris would need to win either Arizona, Georgia, Nevada or North Carolina to avoid a tied election.
