Well this article throws a bunch of different things out there suggesting that, first, Bulgaria will adopt verified electronic voting, and second, that electronic voting is sound enough and ready for deployment. Both of these points are false or unclear at best. Then the blog seems to suggest there is some sort of middle ground between verified voting and non-verified voting and it's OK to make some half-assed step in this direction, which is exactly what the video warns against.

When people talk about electronic voting, typically this means the US-type of voting. And when someone talks about verifiable electronic voting, then they should start by making it clear that this is orders of magnitude more ambitious, it hasn't been deployed anywhere and Bulgaria will be the first country in the world to do it. This is a project of historical scale including the known practical difficulties with the current methods. It should not be advertised like a proven system working in EU and US like it is now. And like I said even if Bulgaria really adopts any sort of verifiable voting there will be so many confused people due to the nature of the process it will skew the results.

Finally, again as the video explains paper vote counting may not be perfect, but it does require more people to involved in the fraud. This is a very important point. Results are available per area and each party makes sure the sum makes sense at least from a small sample.
