The too-close-to-call races for San Francisco district attorney and District 5 Supervisor will not be decided until some 70,000 mail-in and provisional ballots get counted this week. And if Props A and D don't hold onto their 66.66 percent majorities, they will not pass.

The city's Department of Elections estimates there are 70,000 more ballots to count, with 39,000 of those being mail-in ballots that people returned by hand to polling places on Tuesday. Another estimated 14,000 ballots are expected in the mail in the next day — and those all count as long as they were postmarked by Tuesday. And, additionally, 12,500 provisional ballots were cast at polling places as well, as the Chronicle reports.

District Attorney candidate Suzy Loftus's 240-vote lead over Chesa Boudin may grow or disappear as those ballots are tallied, and the same goes for Dean Preston's current 218-vote lead over Vallie Brown for the D5 supervisor seat.

Propositions A and D meanwhile, because they both involve taxes and/or bonds, require supermajorities of two-thirds or better, and in the case of Prop D, there's no room for no votes to out-pace yeses among the mail-in ballots. As of this morning Prop D (the measure to tax Lyft and Uber rides to pay for traffic mitigation projects and Muni funding) had exactly 66.66 percent of the vote.

Prop A (the $600 million affordable housing bond) had a more comfortable 69.5 percent as of Wednesday morning, but that could move as well.

As the Chronicle notes, on good days, the city is able to count about 20,000 ballots per day. So, maybe, just maybe, we'll have a District Attorney and D5 supe by Friday.
