AP: GOP redistricting edge moderated Democrats' 2018 gains

The AP examined all U.S. House races and about 4,900 state House and Assembly seats up for election last year using a statistical method of calculating partisan advantage that is designed to flag cases of potential [?] political [!] gerrymandering. A similar analysis also showed a GOP advantage in the 2016 elections.

When is gerrymandered district assignment NOT a political instrument? Never.

The AP used the so-called "efficiency gap" test in part because it was one of the analytical tools cited in a Wisconsin gerrymandering case that went before the U.S. Supreme Court in 2017 and is part of a North Carolina case ... whether Democrats in Maryland ... Massachusetts ...Pennsylvania ... South Dakota ...Nevada ...Iowa ... Michigan

"Elite" math: Draw me an EU28 district controversy between TWO POLITICAL GROUPS dividing the electorate into a fixed number of legislative seats, and I'll give you that possible Polish "gerrymandering".
