Single day of voting, paper ballots, and purple thumbs. Any precinct without full observation and audit trail is thrown out of the totals. It is the only way to restore the legitimacy of the US Goobermint.
Un-inspectable proprietary software "counting" votes. There should be no such thing. ALL tabulating machines should be mandated to run officially distributed software on machines incapable of connecting to any network. Installed modems or bluetooth capabilities should invalidate a machine and ALL votes on it.
