Michigan clerks rejected 10,694 of the state's 1.6 million absentee ballots during the August 4 primary, according to data released by Michigan Secretary of State Jocelyn Benson on Friday.
"The data demonstrates that thousands of people who cast otherwise valid votes were not able to participate in last week's election solely because the Legislature failed to act ahead of the primary," Benson said.
"With turnout and absentee ballot numbers expected to double or even triple in November, we could be looking at tens of thousands of Michigan citizens disenfranchised if the legislature again fails to act," she said.
More than 6,400 ballots were not accepted because they arrived after election day.
About 2,225 ballots were rejected because the envelopes had no signature.
Another 1,111 ballots were turned away because the voter moved out of jurisdiction after submitting their absentee ballots, according to Tracy Wimmer, spokeswoman for Michigan's Secretary of State Jocelyn Benson.
A total of 846 ballots were also rejected "because the voter was dead."
The U.S. Postal Service warned Benson that the mail delivery timelines for Michigan's primary posed a "significant risk."
"With turnout and absentee ballot numbers expected to double or even triple in November, we could be looking at tens of thousands of Michigan citizens disenfranchised if the legislature again fails to act," Benson said.
? The USPS has sent warnings to states across the U.S. that they cannot guarantee all mail-in ballots will be counted for the 2020 election. Dead people and pets were among the nearly 500,000 inaccurate absentee ballot applications in Virginia. A total of 223,469 mail-in ballots for Nevada's June primary election were bounced as "undeliverable."
