Since 1864, Nevada has never had to hold a special election to replace a sitting Congressman. It does now with the appointment of Congressman Dean Heller to the Senate to replace Sen. John Ensign. But how do we do it? The state enacted laws in 2003 to fill vacancies in the House of Representatives but that law could be problematic. It doesn't explain how the parties are to endorse candidates for special elections. Secretary of State Ross Miller has set out the rules for September's election but not everyone is pleased.
