Thanks to Jerry Brown, ballot harvesting is legal in CA.. I don’t think when Brown signed ballot harvesting into law, he made the distinction that it was only legal for democrats.
...what’s sauce for the goose is again for the gander...
Scott Adams said this: if you want a process improvement, ask a Republican.
So in CA, vote harvesters are legally allowed to “assist” people with their ballots, and go door to door doing so and collecting them and taking them to the mailbox for them.
So CA Republicans improved the process: just set out handy boxes to collect them in places like churches and gun shops, and then no one needs to go door to door to harvest votes.
CA Dems will get smart soon and set up their own boxes in welfare lines, colleges, etc.
