The Economist is publishing an article describing how information about demographics is leading to an algorythmic method of “redistricting” to enable very meaningful manipulation of state-wide votes.
The article provides examples, and even claims “Weirdly shaped districts… are signs that a crime has been committed. Again, start with Florida. This year, the Republican-controlled legislature has proposed a map with 18 Republican-leaning seats and seven Democratic ones. But as the 2000 presidential vote showed, Florida’s electorate is split perfectly down the middle. The map has been rigged outrageously to favour the Republicans. ”
The Article also discusses the cases of Michigan, Texas, and California.
