Montana was won by Governor George W. Bush. Bush won most of the counties in the state, and only obtained less than 40% in three counties. Bush won the highest populated county, Yellowstone County with exactly 59% of the vote. Gore won a total of five counties, and did the best in Deer Lodge County.
Ralph Nader, the Green party nominee, performed very well here, getting 5.95% of the vote statewide. He did very well in the western part of the state, getting over 5% of the vote in most of the counties in the region. His best performance by far was in Missoula County, where he got over 15% of the vote, which was the only county Nader cracked double digits. Nader's performance in Montana made it his fifth strongest state after Alaska, Vermont, Massachusetts and Rhode Island.
As of the 2020 presidential election, this is the last election in which Missoula County voted for the Republican candidate. Al Gore's 33.4% of the vote was the worst performance for a Democrat in Montana since Jimmy Carter in 1980, and no Democrat has fallen under that number since. Gore's margin of loss is the largest for a Democrat in Montana since James M. Cox in 1920.
