Looking past the Brown and Graham contest, this ruling really doesn't hurt many incumbents. If they go for a least change map, which is hard, all incumbents besides Jolly would run in districts which match the current vote by about 3 points.
I think a GOP Rep in the Orlando is gonna take a hit. Grayson's seat is already 62% and there is a lot of Dem voters in the area that were in Brown's seat. Also the 26th will become a few more points Democratic, meaning Curbelo will probably be in more trouble than he actually was. Will probably result in D+2 in 2016.
