The Indiana map really isn't unaggressive. It's an attempt at 7-2; they just did a very stupid job of it.
South Bend into the 1st might have been a bridge too far, but that Indianapolis district is pure incompetence.
If they split up Indianapolis, I guarantee you that in 2014 or whenever the next Democratic wave is, Democrats would have likely picked up IN-04 and IN-05 due to Indianapolis being put into those districts.
I don't suggest cracking Indianapolis. I do suggest putting IN-07 in the correct part of Marion County to suck up the Democrats, and avoid the Republicans that live in the southern area of the county.
