Certiorari.
Ballot-handling cannot escape chain-of-custody outside of elected election officials.
Again, just a simple article detailing California's illegally placing ballot-handling in the hands of nutroots who are not sworn elected election official.
There are state laws nearly everywhere that prohibit ballot 'electioneering' anywhere beyond a polling place set perimeter.
There are a plethora of 2019 off-election primaries in the next 6 months. If someone like O'Keefe can infiltrate the very likely attempt by Democrats somewhere like Illinois to immediately expand ballot dumping and publish the viral video; we have the opportunity to not just end this sedition permanently, but also begin a Federal invest into exactly what happened in Kali, and put rank-and-file Democrats in jail.
This is the missing ingredient - putting these door-to-door shitknobs in prison, thereby warning off any future attempt to subvert elections in this manner. Just in time for 2020.
Are there any non-wacko judges in CA?
And the chain of custody isn’t necessarily much better when the post office is involved. What CA seems to have done is enable voters to deputize someone other than the post office to deliver their ballots to the registrars or polling places or whatever.
To me the surest question is whether fraud can be adequately guarded against in this scenario, which is a version of your chain of custody question.
I agree with the sentiment of your post, but I think they’ve already crashed the gate doing 98, and they ain’t a-gonna pay no toll...
But first; you have to make it illegal.
Of COURSE the vote count is going to go UP if you have a bunch of lazy, potential voters who are just thrilled to be able to 'vote' and not leave their couch!
A friendly face appears at their door to 'help' them.
Now in theory; no PRE or POST selection should take place, but it is SO easy to do! Why not help your OWN party by asking a few innocuous questions? Then the 'volunteer' can either turn in the ballot or 'lose' it.
