Could a groundhog do a better job? 

Based on data shared by Steven J Miller PhD Mathematics (Princeton), now at Williams College,  there were 165,412 absentee ballots sent to registered Republicans that were never returned (this appears to be a factual number.)  Based on a phone survey of 20,000 of these registered voters, it is estimated that 41,000-54,000 were not requested by the voter and 39,000-56,000 were returned by the voter but not received by vote counters. 

In Pennsylvania you cannot vote in person if you’ve requested an absentee ballot and do not bring the absentee ballot to the polls.

What does it mean?

I don’t know, but there are some questions. 

What would the Democratic non-returned absentee ballot day to look like?

What were the numbers from previous years?

Why do I continually hear there’s no evidence whatsoever of voter fraud, but then find this type of information in very obscure places and I don’t see it in in normal places?

Did the people responding to the survey lie?

Did the people that claim they did not ask for absentee ballot, try to vote in person and were prevented?

I am amazed by the lack of interest by mainstream media and by the lack of integrity in the voting system of such a great country.
