I am grateful that under President Biden, the threat is less. However, the threat remains, and seemingly every inch of ground now has to be fought for. The details of this can be seen right here on this blog. But a more detailed, complete, and nuanced guide is given in this tome.
Not only should every government official read this book, but every citizen should be familiar with it. Democracies don't just happen, and they do not survive without watchfulness.
Highly, highly recommended
