In 1872, Jones decided to try his hand at politics as a Democrat but was defeated by William Purman in a bid to become a U.S. representative. In 1874, Jones won a seat on the Florida House of Representatives, winning by only five votes. After gaining independent support, Jones made a second attempt at federal office and, this time, was successful. He began his first Senate term in 1875 and was hailed as an early success and an example of resurgence for the Democratic party in the Reconstruction era. Although criticized for his speaking style, Jones was elected to a second term in 1881.
Permanent vacation
In the spring of 1885, Jones announced he was taking a vacation in Canada and Detroit, Michigan. When the Detroit vacation extended into early 1886, questions started to be asked and gossip ensued. The most popular story was that Jones was pursuing - or even stalking - a wealthy younger woman named Clothilde Palms and was refusing to leave Detroit without her. By April 1886, the speculation was that Jones had become insane. Around that time, the Senate leadership started replacing him on various committees. Although that move drew vocal ire from Jones, he continued to live in Detroit. Florida newspapers were campaigning for Jones to be replaced but Florida's Governor Edward A. Perry refused to take any action, citing, among other things, the lack of concrete rules regarding a senator who would not work but had not been officially declared physically or mentally impaired. Instead, Jones' seat went unfilled until his term expired in March 1887.
After Jones' term – and salary – ended in 1887, his life quickly spiraled downward. By year's end, he had been evicted from his room in Detroit and reportedly became destitute. Doctors informed one of his sons that they would sign a certificate of insanity for legal purposes. In spring of 1888, Jones had reportedly been reduced to common vagrancy. In May 1890, Jones' son was granted permission to have him restrained and a probate court was told that he conclusively suffered from monomania. Shortly thereafter, Senator Jones was taken into custody and brought to an asylum for the insane in Dearborn, Michigan where he stayed until his death over seven years later. Despite rampant gossip and speculation about both his mental state and Clothilde Palms, Jones himself never spoke publicly about either subject. The cause of his sudden decline remains a mystery. Clothilde Palms married a Detroit surgeon in 1889 shortly before Jones was committed. Charles W. Jones is interred in Pensacola, Florida.
