During his term as attorney general , Hadley was the highest-ranking elected Republican official in Missouri . This , combined with Hadley 's success with the Standard Oil Company suit and his record for reform , contributed to his 1908 election as governor of Missouri . His administration enacted penal reform , expanded safety and public health regulations , and established a nurse examiners ' board , a fish and game commission , a game protection board , and a Missouri waterways commission . Many of Hadley 's recommendations for change in other government sectors , such as revenue and public service , were not supported by the Missouri General Assembly . In 1912 , Hadley served as floor leader for Theodore Roosevelt 's wing of the Republican Party at the 1912 Republican National Convention . After the death of Vice President James S. Sherman in October 1912 , President William Howard Taft strongly considered naming Hadley as Sherman 's replacement on the 1912 Republican ticket , but Taft ultimately did not select a replacement before the election was held
