Speaking of whiskers, Hughes was also the last major-party presidential candidate to wear both a beard and mustache, and by losing wasn't able to delay the trend of clean-shaven presidents in the 20th century after Taft. He wasn't the most recent presidential candidate with facial hair, however. That distinction currently belongs to the mustachioed Thomas Dewey, loser in 1944 and '48.
According to the entertaining web site "Facial Hair and Presidential Elections, "It is said that Hughes 'grew his famous beard in 1890 in the interest of efficiency - to save trips to the barber.' Theodore Roosevelt, reconciled with the Republican Party, unenthusiastically campaigned for Hughes, whom he called "Wilson with whiskers." Hughes apparently went to bed on election night thinking he had won, and was woken in the morning to learn that he had lost."
This is another amusing article about presidential facial hair.
