Online voting could be done securely over the network and could be authenticated with a certificate associated with one's voter registration that's anonymized in a way that doesn't reveal any information about the voter other than whether they have already voted.
Also, it can be an option in addition to voting in person or by mail (like you can do now with taxes).
There's a lot of handwaving in this sentence about what can be done. We can't even secure computers when the fate of the entire world _doesn't_ depend on it. You think we can do a better job when control of a nuclear power with the world's largest economy rests in the balance?
> like you can do now with taxes
I'm not terribly worried about the consequences of someone filing my taxes for me.
This is hyperbole at best. In most cases, international policy does not change all that much regardless of what major party member happens to be president of the US.

Unless you have taken the time to fine tune your payments such that you don't receive a refund or owe a significant tax payment, then someone else filing can effectively get your refund, or put information in there that can land you legal trouble or have you owe a significant payment when you actually do not. That said, we have been able to file taxes online for many years now. It would be nice if we could get with the times and do the same for voting.
