There are documented issues with many existing electronic voting systems. E-voting encompasses a lot of different types of system that can involve computers in the chain, and not surprisingly all of them are equal.
There have been a few discussions around voting on HN recently, and that's good. It's an important topic, as trust in the integrity of elections is vital for democracy. There's a lot of existing material out there about verifiable and auditable voting systems, especially in the wake of the 2000 US Presidential elections. I encourage you to take a look at what's out there. It can provide a great foundation for discussion.
