Does California Need Federal Election Monitors? If so, be neutral, be objective, and don’t interfere with the process.

There's been a lot of discussion about federal election monitors in the Nov 4th election here in CA. Here's my take, on my Election Science Field Notes Substack.

Resilient Elections Good training and good process yield good results

Been out in the field with election monitoring, and learned some important lessons about how election officials can build resilient elections. It's on my Election Science Field Notes, on Substack! @caltechlcssp.bsky.social
