A smarter thing to do would be to create a selection pool defined as any registered voter over the age of 75; and from that pool they choose their election technology board. And that board procures the election system based on the budget the legislature gives them. That is, the budget is the budget only, it doesn't say anything about what technology or brand is used, the only attachment is that funds are used for the state election system. If someone over 75 can't understand how our election system works, we're screwed, and in fact we've seen how voting systems have failed, have altered the outcome of elections, and because they had no paper trail, and no meaningful way to do recounts or audits there's no recourse.
Would you feel better if the government designed the machines? A lot of people would probably feel worse.
Right now, you have each state's board of elections making decisions - they get observed by both parties so that they can all sign off on what's happening. Idk. You can never eliminate the possibility of fraud. I just think the likelihood of all of these actors colluding is really low... I mean congress can't even pass a budget.
I'm not saying I prefer Diebold, but I certainly prefer it if the only other option is the House/Senate $PARTY Caucus.
