1. ALL of those ballots were returned? Really?
2. Biden won 77% of them? Really?
Missed the excerpt in post #5. OK, so 85% of the mail-in ballots were returned. Really? Seems like a pretty high number, but maybe its normal... Still not buying that Biden got 77% of them though.
Now, THAT is the kind of statistically implausible response I want to read.
We do know that Republicans by a huge number, prefer to vote IN PERSON. Democrats on the other hand, prefer to vote by mail.
To answer that, we need to know how many percent of Democrats were likely to vote by mail. Without that data, we can’t answer that question.
