Paper voting at least has a trail. Electronic voting leaves no trail at all.

Re: "voting the graveyard" there are following ways to prevent it:

An election monitor can manually count people coming to the polling station and compare it to the number of ballots taken out of the box. Monitor can observe how those votes are counted, and get a signed document with results. After counting the votes across the country, he can compare his paper document with official published results, filtering them by his polling station. Every step is verifiable.

Also, every voter must leave a signature. Signatures also can be verified.
