[UPDATE 9:50pm: Tonight's drop grew the margin to 716 votes. 211 ballots came in today.]
As of Sunday evening, the margin is down to 695 votes, in favor of a NO. The auditor says the ballots received are starting to drop to a trickle, with only 341 received yesterday. But the margin is 0.36%,
small enough to trigger an automatic machine recount. [UPDATE: A commenter points out that the linked rule may not apply to local measures. I've sent an email to the Pierce County auditor to find out. See the correction.]
Chris Karnes at Tacoma Tomorrow has the city-by-city breakdown of numbers through Friday. Tacoma and the relatively prosperous places near the water are the ones leading on this issue. It’s also interesting to me that Joint Base Lewis-McChord is breaking against the measure given that the on-post shopping options aren’t subject to sales tax, and given how strongly it went for Sound Transit 2 in 2008.
