Election poll site manager explains US election systems

In a departure from our normal coverage, I decided to bring on Mark Thompson, who was the Site Manager for the election polling site I volunteered at last week. He gives us insight into how elections are managed in the US, and what we do to prevent fraud and ensure the overall integrity of the system. We talk about the technology used on the front end of the polling process, which in San Diego county including Electronic Poll Books (EPBs) and Ballot Marking Devices (BMDs). We then also talk briefly about the checks and balances in the actual counting process. Although this is a departure from our normal fare, I think a lot of people will benefit from the info we discuss.Also, I also posted a blog post about this topic here: http://www.backupcentral.com/why-its-really-hard-to-rig-a-national-election/
