At their Central Committee meeting over the weekend of April 30-May 1, the Washington state Democratic Party amended its 2012 delegate selection plan (prior version). Among the amended provisions was a change in the proposed caucus date. The earlier version had pinpointed Saturday, April 7 as the date on which the party would select delegates for the purpose of nominating a presidential candidate. However, that date has now been changed to Sunday, April 15.
Washington will now share that date with Alaska Democrats holding caucuses on the same date.
Hat tip to Tony Roza over at The Green Papers for the news. They posted the news of the change last week, but the Washington Democratic Party took longer to confirm the news on their website.
