SEATTLE -

Dozens of problematic ballots may determine the fate of an initiative to establish a $15 minimum wage for many workers in SeaTac.

The ballot measure was winning by just 43 votes Tuesday as officials in King County resumed counting ballots. There are likely hundreds more votes to count due to the lengthy ballot-collection process caused by the state's vote-by-mail system.

The campaigns say they also have a list of about 150 voters who had signatures on their ballots that did not match records. Both sides are working to contact favorable voters who have signature problems, asking them to return paperwork that will finalize their ballots.

Other ballots in which the voter's intent is in question will be resolved during a canvassing process in the coming days.
