There is an election security fight brewing in Georgia, where Sec State Brad Raffensperger's bet on securing vulnerable voting machine software by other means for 2024 is setting off a firestorm of criticism from security experts. My story below: politico.com/news/2023/06/2…

I like the quote at the end by John Sebes "We’ve got to be able to have a conversation about that without being wrapped up around the flag of MAGA conspiracy theorists" politico.com/news/2023/06/2…

Today's the 1st day of class at University of Michigan and we're in hour 24 of a major IT outage. Despite the disruption, it's been great to see colleagues innovate and help each other work around the downtime. Big thanks to everyone at UMich ITS who's been up all night to bring us back online.

From a security perspective, elections are much safer when there's a decisive outcome than when they hinge on razor-thin margins in a few states. But what about next time? How many voters will continue to call for necessary election security improvements?
