On March 4, the North Carolina State Board of Elections set dates for the re-do of the U.S. House of Representatives election for the 9th district. The primary will be May 14. If any party needs a run-off primary, the run-off primary will be September 10, and the election will be November 5. If no party needs a run-off primary, then the election will be September 10.
These dates are not identical to the dates for the special election for the 3rd district. Those dates are April 30, July 9, and September 10.
The filing period for NC-3 is this week, so it would have been impossible to match the schedule for an election called this week. The NCSBOE also wants to be able to monitor the election in NC-9 and needs to staff up.
The filing deadline for inependent candidates in NC-3 is April 30, the same day as the primary.
Since the general election in NC-9 will be two months later than in NC-3, it would seem logical to make the independent filing deadline later as well, but I don’t know if that will happen.
Independent (unaffiliated) filing period for NC CD9 is May 14, the date of the primary in that district
The petitions for independent candidates are not due on primary day in North Carolina. Instead they are due 15 days before the primary. Petitions must be submitted to county election boards, and then the county has 15 days to check the signatures and get the results to the State. The law emphasizes the date the petitions are due in the State Board, but that is not the true deadline for collecting and submitting signatures.
