Politics
In 2010, the city was cited by the Georgia Secretary of State's office for failing to hold regular elections in 2009, as well as being unable to document any elections from 2005 through 2007. A De Soto councilmember apologized by saying that the city simply "forgot" about the need to hold an election. Facing a number of state violations, the city promised to remedy the situation permanently by outsourcing the elections process to a third party. The state provided that the 2009 election must be held by March 2010.
