Or how about all the issues over running out of paper ballots, long lines, etc. With electronic voting you could have everyone pre-enter their vote electronically & just "drop" it off by scanning their phone & getting a printed receipt they can use to confirm their vote was recorded correctly cryptographically.
It is possible to actually design secure electoral systems that actually protect the integrity of the election better (better anonymity, better traceability, better auditing, less error, more accessibility, etc, etc, etc). Convenience is also important; there are even ways you can potentially design the system to run on semi-trusted hardware which means lower cost & more polling stations, easier access etc. This rhetorical argument of making fun of the idea as "we can wait a couple of days for the results" completely ignores the actual advantages of such a system. It also completely ignores that a paper trail isn't mutually exclusive from electronic voting.
The challenge is in making sure the process for creating these systems isn't corrupted, especially by technologically illiterate legislative leaders who don't seem to place any of the most basic protections that experts recommend. They also don't have the balls to hold the voting companies to task for designing secure systems; somehow it's a non-issue for the same companies to do the obviously right things when it comes to their other customers (banks).
