Nully's modest proposal to end voter fraud:

Paper ballots (zeugma adds) with human readable marks. They may be computer generated, and/or computer counted, but there must be an audit trail of each vote. H/T zeugma
Purple fingers (needs something to prevent an absentee voter/early voter from re-voting at the poll, maybe blockchain, also maybe a mugshot showing the voter an the photo ID taken at sign in?) H/T for-q-clinton
Mandatory free on demand BIOMETRIC (iris scan, nobody ever left their irises at a crime scene!) photo voter ID card, with a database that instantly flags for arrest anyone seeking multiple IDs. Change of name or address? Simply have your old card voided when you apply for the new one.
No precinct reports their totals until ALL precincts report they have totals. This prevents the last-to-report precinct captains from knowing how much to fudge a report to give a win to their preferred candidate while maintaining some slight semblance of credibility.
Repeal Motor Voter.
End same-day registration where it exists, and allow ample time between registration and election for vetting of credentials of registrants.
Instantly deport any non-citizen who registers to vote. Permanently ban from re-entry any non-citizen who actually votes.
Put a little ⩍ next to the names of those registered voters with death certificates, and detain and put a 72 hour psychiatric hold on anyone claiming to be a dead person...
With the exception of absentee ballots, end early voting. Every voter deserves and has a responsibility to know the latest information before they cast their ballots. H/T WildHighlander57
Absentee ballots must be vetted and counted 10 days before the polling date, with the results secured until the date of the vote. H/T octex
All voter rolls are automatically and completely purged ten days after the Presidential Inauguration. Reregistering to vote every four years is not an imposition. H/T The Chid

Mexico has voter ID cards required to vote, and when you vote, they punch a hole in your card to prevent multiple votes in the same election.

I don't know if you get a 10% discount after you've accumulated enough punched holes…

Of course, all this would only apply to Federal elections, for federal offices, as that is the legitimate concern of the federal government.

Let the states who have local authority use whatever system they wish to force the elections of their favorite sons and daughters to alderman, mayor or goobernor. They can do it the cheap way, by just following the federal rules for all voting, or they can have separate ballots for local and federal. Their call. It's a free country, ain't it?
