How do you dump the firmware from a "secure" voting machine? With a $15 open source hardware board

Call me paranoid, but I’d love to know whether any hacking of high tech voting machines put Donald over and into office – ditto for the GOP success with the congressional elections. Then, after we make the machines secure (and, for the scan machines at least, maintain the paper sheets), we maybe can worry about who exactly did the hacking.
That a number of American voters believe the BS in the social media is far more disturbing than the Russians abusing those networks.
But that’s me. Clearly, the DNC and corporate media disagree.
