I think you're being overly pessimistic. Yes, people can file lawsuits over every little thing, but they can be dismissed with equal ease as well. Given the expected margin of victory, it serves the Dems little advantage to contest the results.
Their strength now lies in falling back and re-grouping. There's a primary in March, and of course the big one next November to prepare for. From now on, Arnie will be the whipping boy for everything that is horrible about the Repubs.
LOL. I thought I was being optimistic. I'm saying that the Democrats won't have the ability to try to have different recount standards in different counties. And I don't expect it to be close enough for a recount anyhow.
Here, I'll go out on a limb:
Prop 54: Yes 55%, No 44%
