As Rebecca Solnit writes in The Guardian:
“The United States’ voting system is an incoherent patchwork of systems of varying degrees of reliability, many with easily hackable machines, all managed by local election officials of varying levels of probity and competence on computers with no notable security.”
And let’s not forget dictator Trump and his thugs:
“Some participants in the recount in Detroit are reporting that representatives of the Trump campaign are intimidating and interfering with the volunteers and paid ballot counters.”
And did you know about Michigan’s perversely anti-democratic statute?
“The state has a law preventing recounting votes where there are discrepancies between the machines and the hand-tabulated ballots, which is exactly what you get in a poor city with old voting machinery.”
As Jill Stein says in the piece, it’s a law “precluding a recount exactly where you would need it.”
