Most districts and states are not good about having accurate up-to-date voter rolls.
Seems Florida, and a few other states did a lot of work to clean up the lists of valid voters at valid current addresses- unrelated to Covid.
So in some areas, ballots are sent for everyone registered- often in error.
Requesting one from your current mailing address makes for more control.
e.g., I used to live in Nevada and never 'unregistered', so are they sending me a ballot at my old address? Is this cross referenced with California? Will I be getting one at my old Ohio address too?
If anyone had some unbiased factual info that can explain, I'd appreciate it!
It would need to go state by state since they all have their own processes.
I suppose people would only be interested in the States in play- so about 8 or 9 of them?
