As mentioned in the comments, Jane Kidd has qualified for the Senate race, and now she is challenging the redistricting in a lawsuit filed Wednesday. Because of the emergency hearing in a U.S. District Court, the judge has extended the qualifying period for Senate 46 and 47 and 13 associated House districts until May 5. The hearing will be next Tuesday in Atlanta.
We've discussed our thoughts on the merits of a lawsuit previously, and so I won't go into that again, but I will say that Kidd certainly has a strong advocate for the suit: her lawyer is Emmet Bondurant, Georgia's #1 "Super Lawyer" for the past three years straight (yes, this is an actual list, compiled by Law and Politics magazine in conjunction with Atlanta magazine based on attorney suggestions). Go, Super Lawyer, go.
