National: How will Big Data change gerrymandering? Both parties are eager to know what you do online | Salon
When you exit the Pennsylvania Turnpike just north of Pennsylvania, on Main Street in working-class Norristown, you’re in the overwhelmingly Democratic 13th congressional district — at least for a couple of miles. The help-wanted signs are in Spanish; people walk past the Premier Barber Institute, bail bondsmen, and the 99-cent stores wearing branded short-sleeve shirts from their chain-store jobs. But come around a corner and up and hill and suddenly the neighborhoods turn leafy and green. Suburban-looking dads walk large dogs with flowing tresses. The houses are lovely and set back from the road. This three-quarter-mile stretch is in one of the nation’s most infamously gerrymandered districts, Pennsylvania’s reliably Republican seventh, a one-time swing district so wildly drawn that it resembles Donald Duck kicking Goofy. Signs warn drivers not to tailgate.
