GMO Labeling Backers Outspend Foes In Washington

Correction 8/22/13: A previous version of this story contained errors. It overstated the contributions received by the Yes on 522 campaign and the share of donations received from Washington state. The Yes campaign has amassed $3.5 (not 3.9) million, with 79 (not 71) percent of the funds coming from out of state. The nonprofit MapLight, based in Berkeley, Calif., informed us on Aug. 21 that it had double-counted some contributions, which led to the errors.
