Seabrook traces the history of gerrymandering beyond its supposedly American origins to the English tradition of 'rotten boroughs,' dating to the 13th century, with small numbers of voters attaining electoral power out of proportion to their numbers and members of Parliament propped up by corrupt measures...As Seabrook notes, the 19th century was the heyday of gerrymandering as practiced by nearly every party, so that in one Ohio election, as a contemporary observed, if the Whigs won the state by 10,000 votes, they would still earn only seven congressional representatives while their opponents would have twice as many with the same count...In a concluding call to action, the author writes: 'How much do you really know about redistricting in your state? If the answer is not much, well, that’s what the career politicians already huddling behind the scenes with teams of redistricting professionals, attorneys, political scientists, and strategists are hoping for. Democracy dies in darkness'...Valuable reading for voting rights activists..
