In the Presidential election, Democratic Governor Woodrow Wilson of New Jersey defeated Republican President William Howard Taft and former president and Progressive Party nominee Theodore Roosevelt. Socialist union leader Eugene Debs, running his fourth campaign, took six percent of the vote. At the 1912 Democratic National Convention, Wilson took the nomination on the 46th ballot, defeating Speaker Champ Clark and several other candidates. Roosevelt left the Republican Party after an unsuccessful challenge to Taft at the 1912 Republican National Convention. Though Wilson carried just over 40% of the popular vote, he dominated the electoral college and won a greater share of the electoral vote than any candidate since Ulysses S. Grant in 1872. Wilson's election made him the first Democratic president since Grover Cleveland left office in 1897. Roosevelt's candidacy finished second in the popular vote and the electoral college, the only time a third party candidate accomplished either feat.
