The election systems are managed at the state level exactly as they should be. Corruption has a much lower chance when there are barriers.

That said, there should be national minimum standards for the elections.

Chain of custody is something all elections adhere to in the US, but if it's not a federal requirement, it should be.

What's really needed are hand marked paper ballots, electronically counted using open, independently audited machines with no network connectivity (obviously). "Scantron" style machines That should be a minimum requirement.

Nobody stole the election from the doddering old fool in 2020. Internet bullshit doesn't stand up in court where they do have evidence standards.

Edit: Back on topic ... individual stock trading by representatives clearly should be illegal. And apparently we need more independent watchdogs with better protections against a puppet who mindlessly goes along with the last person to manipulate them.
