But other organizations have done similar things in the past to affect change, so why not do it here?
Basically, instead of complaining about how unsafe and insecure voting is, start a website called something like 'cockblockthevote.org' and detail how to cheat at voting on a state-by-state sort of setup, where each state's districts will have the machines they use with a link to all the vulnerabilities and how to 'hack the vote' with that machine. I'm sure a bunch of the research can be done here on slashdot by just browsing election years and all the notes on things like diebold vulnerabilities.
A site like this would get change a lot faster than security experts whining about it, IMO. I would even donate to whatever group started doing it but the truth is I just don't have the time to DIY.
