Death to the Gerrymander
The thought experiment I've liked in the past is...<p>Say you have a 55/45 state, with 9 congressional districts. Roughly speaking, what is most fair? A 5/4 district split? Or, each district being 55-45, i.e. 9/0?<p>If I'm reading it right, it sounds like the efficiency gap would mean that 5/4 would be more fair, but that would actually require drawing districts in a way that pays attention to the political and demographic makeup of the geography.<p>I get that for many states, if the Democrats had the 55, then current gerrymandering means that they might only get 2/7, or two out of the nine candidates, which seems wildly off no matter how you look at it, but still, I have trouble identifying the principle of what fair actually <i>is</i>. And I don't like the answer of just arbitrarily picking a math formula that is used the same way everywhere. Because, in the absence of a principle behind it, it could be just as distorted. For instance, if 5/4 is more fair, then a geographically blind districting program could very easily end up with similar blended districts leading to a 9/0 state.
