The simple answer? Money and jurisdiction. There's an article[0] with a powerful quote on the subject: "There is no one election in the United States, there are thousands of independent elections. ... They’re run with their own policies, and their own processes, and, frankly, in a lot of ways, their own vocabulary." Machines are usually bought by local jurisdictions. Some states cover the costs for all elections; some for only some elections; over 6 cover nothing. In any case, local jurisdictions are faced with a conundrum: do we spend money for something that's used only a couple days a year, or fund more immediately beneficial programs (roads, aid programs, etc.)? Budgets can't even keep up with replacing equipment, let alone thorough code and security reviews. Assuming the administrators even recognize what kind of work needs done. It's outside their experience, and when you start considering the kind of attack vectors that freaking nation states can literally create, even the best efforts of well-intentioned election officials are going to be wholly insufficient. And when nation states that are willing to put in the effort are the threat you're protecting against, everything changes. Individual states are unlikely to try and setup the kind of review that you're looking at. Or--possibly--even realize that they need to. It's expensive, and the people they're relying on to inform them about these matters are often the people selling the machines. Worse, you're looking at at least 50 separate efforts to secure voting machines. They may, or may not, somehow wind up coordinating with each other. The federal government could, but states guard their control over elections fiercely: just look at how almost all of them told the Obama administration to go pound sand when DHS warned them of potential hacking attempts. Unless there's a major, undeniable breach, I don't expect much to change anytime soon in most states. Even then, we'll probably see a shift to paper ballots rather than the sort of hideously expensive expenditures needed for the sort of rigorous IT security efforts we now know are necessary for electronic voting in the current threat environment. Otherwise, we'll be lucky to see piecemeal incremental improvements when individual states get around to them. 0. https://www.propublica.org/article/election-security-a-high-priority-until-it-comes-to-paying-for-new-voting-machines https://www.propublica.org/article/election-security-a-high-...
