On June 19, South Carolina Governor Nikki Haley signed SB 2. See this story. Candidates for state and local office who fail to file certain documents relating to their personal finances will no longer be barred from ballots. As the Governor mentioned, in 2012, 200 candidates were kept off the ballot because of trouble filing forms relating to personal financial interests.
The big change is that candidates will now file with election commission rather than the parties. It will be easier to switch to Top 2 with that change.
