This question should dog every candidate who reaches the general, besides Sununu and Scott.
Why single out those two?
I'm guessing Napoleon's logic is Florida has a "Fair Redistricting" law (That Republicans ignored and got away with for 2 cycles), and Sununu will be up for election again in 2020 and gerrymandering questions should be saved till then.
Of course the answer is that gerrymandering is too nerdy and unsexy of an issue for the media to pay attention to. Takes too much time to explain, doesn't make for a good clickable headline.
