It was last reported that there were 3,539 more ballots counted in King County than voters who cast them. The discrepancy is actually much larger.

The 3,539 is only the net. This comes from having roughly 1,500 more voters than counted ballots in some precincts, and about 5,000 more ballots than known voters in other precincts.

[This picks up where I left off in the post below about Precinct 3301. I can find only 41 precinct changes among counted voters in the Dec. 29 file since the Nov. 1 file and these appear to be provisional voters who corrected their precincts at the polls. Conclusion: in certain precincts there are about 1,500 more known voters who cast ballots that were accepted than there are ballots that were counted in the manual recount].

Sounds like good old Chicago style ballot stuffing to me.
