Update (8/18/20): Later on August 17, Martha MacCallum corrected her misinformation about Michigan’s 2020 state-wide primary election, saying that the ballots she previously scandalized were “from people who passed away after they voted, and to correct myself, those were also eliminated. So there’s no sign of foul play in that vote.” However, she continued to claim “in the big picture” that universal mail-in voting carries “concern” of voter fraud.
On August 17, Fox News anchor Martha MacCallum said on Outnumbered that “there is reason to be very cautious” about universal mail-in voting for the 2020 general election, because Michigan “had 864 dead people vote” in the August 4 state-wide primary election. “It’s an intentional action. It’s not a mistake,” MacCallum warned.
The problem with MacCallum’s serious warning is that those 846 Michiganders (not 864) “died after casting their absentee ballot but before Election Day,” as the Michigan secretary of state’s website clearly states. Actual journalists have already corrected this misinformation, which is not evidence of voter fraud of any kind.
MacCallum is scheduled to co-anchor Fox's coverage of the Democratic National Convention.
