1916 Republican National Convention: The 1916 Republican National Convention was held in Chicago from June 7 to June 10.  A major goal of the party's bosses at the convention was to heal the bitter split within the party that had occurred in the 1912 presidential campaign.  In that year, Theodore Roosevelt bolted the GOP and formed his own political party, the Progressive Party, which contained most of the GOP's liberals.  William Howard Taft, the incumbent president, won the nomination of the regular Republican Party.  This split in the GOP ranks divided the Republican vote and led to the election of Democrat Woodrow Wilson.  Although several candidates were openly competing for the 1916 nomination—most prominently conservative Senator Elihu Root of New York, Senator John W. Weeks of Massachusetts, and liberal Senator Albert Cummins of Iowa—the party's bosses wanted a moderate who would be acceptable to all factions of the party.  They turned to Supreme Court Justice Charles Evans Hughes, who had served on the court since 1910 and thus had the advantage of not having publicly spoken about political issues in six years.  Although he had not sought the nomination, Hughes made it known that he would not turn it down; he won the nomination on the third ballot.  Former Vice-President Charles W. Fairbanks was nominated as his running mate.  Hughes was the only Supreme Court Justice to be nominated for president by a major political party.  Fairbanks (as of 2016) was the last former vice president, to be nominated for vice president.
