OLYMPIA, Wash. (AP) — Vermont Sen. Bernie Sanders and former Vice President Joe Biden were virtually tied in early statewide returns in Washington’s vote-by-mail presidential primary Tuesday night,  but it will take days to receive and tally all the votes. Of the six states voting Tuesday, Washington _ with 89 pledged delegates at stake _ offers the second-highest number of delegates to be divvied up, behind Michigan's 125. Democrats are using the vote-by-mail presidential primary moved up this year from May _ for the first time to allocate delegates instead of the smaller caucuses used in previous years.
