White House for One, Please

Although many other commanders-in-chief might have acted single, James Buchanan was the only bachelor president in US History.  Despite having a fiancé, and several romantic pursuits on record, Buchanan's bachelorhood may not be so cut and dry ... Buchanan may have been bisexual or gay.  According to professor James Loewen of Catholic University, Buchanan enjoyed the company of companion William Rufus King, also single, who had also served as the only bachelor Vice President under Franklin Pierce.  Contemporary critics called King Buchanan’s better half, his wife, and Aunt Fancy.  Some people even snickered that they were Siamese Twins, slang at the time for homosexuals.  Little can be learned from Buchanan himself.  He ordered his papers burned upon his death.
