From Katie Hickox:
There are still over 1 million uncounted votes—2/3 of them are provisional, roughly a third are Vote by Mail ballots: http://www.sos.ca.gov/elections/2012-elections/nov-general/pdf/unprocessed-ballots-report.pdf
I doubt that the provisional ballots will really get counted, and there is no way to confirm that our votes are really being counted accurately.
Prop 37 is still losing, but by a much narrower margin. It’s losing by that magical 3% which seems to be the perfect figure to assert the margin of victory.
