Computer Programs Rig Elections

I don’t know how interested this community would be in this topic, I don’t mean to be talking politics so much as technology and decision mechanisms.

According to this programmer’s testimony, voting machine companies requested that their programmers make it possible for the companies to rig elections, while in communication with elected officials.

If there is a discussion of how worthwhile taking the time to vote is, this may be worth knowing.

This is something that I expected to be true beforehand, but I am wondering: How reliable is this testimony? What are other LWers’ prior and posterior probabilities of elections being rigged in this way? Is it worth trying to do something about this, and if so what?
