Excerpt:
By Tuesday night in California, the ballots will be cast, but the results for many races may remain uncertain for days, even weeks.
It is a familiar waiting game that is unique to the state, tending to prompt public scrutiny and debate when major races or hot-button issues are at stake.
But the delay is largely connected to the fact that most of the state’s 22 million registered voters cast mail ballots — and to an extensive review process that requires more than placing a ballot through a machine.
