Not true. This was supposed to be an automated strike list. You check off your voters as they come in to vote, and if they haven't, you give them a call (or even a personal visit) and say "hey, get your butt to the polls". Getting out your own vote seriously matters.
Whether this thing would have been enough to sway the election had it worked, I don't know, but it certainly didn't help the Romney campaign (and probably hurt some of the downticket races as well).
