Tens of millions of US voters use closed-source voting machines during our elections. The companies who make the machines are generally a little too friendly with the Republican party (Diebold, Premier Election Systems, or whatever they recently changed their name to).

I'm shocked at how few people care that so many votes are "counted" through Republican-friendly voting computers.

Funny, I googled "programmer testifies..." and the first autocomplete was "...about rigging elections": https://www.youtube.com/watch?v=tjvtSquZkhs

Journalist Greg Palast also has evidence of electronic voter in Ohio in 2004. (Disclaimer: I have not delved deep on his claims, but the mere fact of their plausibility is deeply concerning.)

The method is widely known, but last weekend there were election with new system for reporting protocols from electoral commisions etc. and it appears to be quite huge swindle since it's been made in three months before elections and failed as fuck. Finally some of votes needed to be counted in Excel.

Feel free to ask about details, because I'm from Poland and hadn't found any sufficient article about it.

That's a pretty good article in Polish, tackles the issue from more than one perspective: http://niebezpiecznik.pl/post/problemy-w-pkw-zliczanie-gloso...
