Congress

"In contrast to North Carolina's Republicans, Indiana's did a remarkably good job of drawing sensible district boundaries. The same holds true for Nevada's Democrats, although with only four districts, the district boundaries in Nevada are dictated to a large degree by the state's borders." (America’s most gerrymandered congressional districts, Christopher Ingraham)

We know that gerrymandering works best in small, oddly-shaped, non-compacted congressional districts, and although Indiana's congressional districts are oddly-shaped, they are still large enough to prevent gerrymandering from occurring. Nevada on the other hand, has one the largest and most "normal" shaped congressional districts in the country, which would explain why gerrymandering is not an issue in that state.

I chose this passage because it illustrated the extent to which a congressional districts size, shape, and compactness can affect the probability of gerrymandering occurring. Seeing the Gerrymander index scores, 113th congress map really put into perspective how much gerrymandering is actually occurring around the country.
