The senator said moving Nebraska to a winner-takes-all system "could be the difference" between Kamala Harris being president.

A top Donald Trump ally is pressuring Nebraska Republicans to award all of their state’s Electoral College votes to the statewide winner, a late-stage rule change that could potentially help return Trump to the White House.

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.

The South Carolina senator wants the governor to call a special session to put forward a bill making Nebraska a winner-take-all state in the Electoral College.

Nebraska is one of two states that award some of its electoral votes by congressional district. A vote from the Omaha area is part of Harris’s easiest path to victory.

Donald Trump believes he will win four electoral votes from Nebraska, but it’s the fifth one that he is increasingly fretting about – leading the former president and his Republican allies to mount a last-ditch effort to try and change state election law only weeks before ballots are cast.

Trump's allies want the state to move to a winner-take-all system for its Electoral College votes to make it harder for Harris to win.
