I'll link to Florida but if you click "Home" above you can check out other states, and the national tally:

At the Florida page click "Mail Returned" and then at bottom use page advance to reach Seminole. They are still way behind most other counties. Currently 46.5% return rate while many counties are well into the 60s%.
A week ago today I thought Seminole ballots had not been received, since they were more than 10% behind any other county. Made no sense. I contacted many people including the Biden camp. I posted a thread in General Discussion here. Finally one journalist responded to me and said it looked like Seminole simply was not processing and counting mail ballots yet, unlike the rest of the state. Then the following day I found the link indicating they didn't begin until Wednesday.
Despite that 22,000 claim I think the ballots have been received and are just sitting around somewhere yet to be counted. Seminole had very high turnout rate of 78.5% in 2016 so this year logically it should reach at least that level if not into the 80s.
