On April 15, 1794 US Vice President John Adams in a letter to his wife Abigail described the vice presidency as "the most insignificant office the invention of man contrived, or his imagination conceived." Adams would later become US second President after George Washington.
And even though a lot has been done to bolster the office described as a breath away from ultimate power, including naming it Deputy President, as opposed to vice, and having the laws provide a joint ticket as is the case in the US and Kenya, any holder of that office ignores Adams' words at their own peril.
