I am not too familiar with all of this, but recently on KGO talk radio, there was a host detailing, in layman's terms, with the pitfalls and potential flaws, present and future of electronic voting. There will always be someone, out there, with the PIN, to access the servers, "THE BACK DOOR", who could potentially access and maybe change the outcome of the voting process; the outcome of the election; the outcome of the winner. The outcome of history? Will this be the future of our election process? How secure will we really be?
