There's nothing conspiratorial about it. There is no other possible motive but the corruption of voting machines, not that we should use those at all anyway.
I wouldn't say there's nothing conspiratorial about it, but it has more to do with run of the mill corruption, incompetence, and the universal practice of always picking the lowball bidder even when they provide an absolutely defective product.
Hey now, not really universal. Even exempting pork barrel stuff. US just has hella' incentive to cut corners on a lot of things gov't funding wise, due to that whole "we keep refusing to raise taxes" thing. Personally met a fair few more than one acquisitions/contract-seeking type critter in public works say they'd
love to hire someone that's better than the absolute baseline, even if it cost more, but it can be complete goddamn misery to fit anything major into the budgets a lot of these areas are workin' with. And particularly when it's something that's used like maybe a week or two every other year or so, and
doesn't involve something that's going to directly kill people if it doesn't work at 100%, well...
E: Also extra bonus fun time rolls in when some degree (sometimes relatively little, sometimes almost entirely) of the ones who ultimately hold the purse strings for that area are
elected officials. A common source of kvetching vis a vis fanfiction is the absolute lack of qualification and quality control on what's produced/who's writing/etc. What we're talking about is basically the governmental equivalent :V
It can make for fun times. Actually had an illiterate alcoholic elected as mayor of a town near me, a handful of years back. He didn't last the full term
E2: And that wasn't hyperbole or exaggeration. Literally someone that'd done a round or two through rehab (it didn't stick) and was not able to read.
