I took the reference to TEMPEST to mean that the good guys were listening to the ESS (Soros-owned) voting machines in Alabama in a sting operation surrounding the Moore/Jones Senate run-off.
The electronic surveillance counted the votes by listening to the touchscreen x-y coordinates that were actually "touched" by the voter and then compared the tally to what that machine or precinct actually reported.
This would prove voter fraud and machine tampering.
