The Washington Post is reporting that the Nebraska legislature is considering a bill that would revert the state to winner take all for its 5 electoral votes. If it passes, it would be enacted for the 2016 presidential election.
Nebraska and Maine are the only two states to deviate from winner take all, where the popular vote winner of the state (almost always) receives all the state's electoral votes. In the case of these two states, two electoral votes are awarded to the popular vote winner, with one going to the winner of each individual congressional district. There are three districts in Nebraska and two in Maine.
Nebraska adopted this method in advance of the 1992 presidential election; Maine enacted in time for the 1972 election. Only once has this method made any difference. In the 2008 presidential election, Barack Obama won the popular vote in Nebraska's 2nd congressional district, winning one of the state's five electoral votes. It was the first Nebraska electoral vote to be awarded to a Democrat since the landslide 1964 presidential election.
