This is just ridiculous.
The defense offered in this story (and many others) is that "There are no known instances of fictitious people actually voting...". Are you kidding? We're supposed to shrug off bogus voter registrations as unimportant unless there's an actual vote? There's nothing suspicious about registering non-existent (or dead, or ineligible) people to vote?
So it's OK if I pollute my town's voter rolls with hundreds of false voter registrations unless (until) somebody actually votes under a false registration?
It doesn't matter that the election workers have to deal with the noise of bogus registrations? Faced with reports of bogus registrations, I would expect (hope) that election workers would be more careful vetting voters on Election Day. But maybe then we'll hear that voters are being "harassed" or "suppressed".
Try this on as a conspiracy theory:
ACORN (or somebody else) contrives to falsely register thousands of bogus voter names, and they (and the press) shrug it off as "not real voter fraud, because nobody has actually tried to vote (yet) under a bogus registration."
But election officials, faced with reports of bogus registrations, are compelled to examine voter credentials more closely on Election Day.
"Closer examination" of voter credentials is deemed by some to be "voter suppression."
So we're faced with two possible outcomes (under the assumption that massive registration fraud has taken place): many fraudulent votes are cast, and/or there are charges of "voter suppression" when thousands of voters (most or all legitimate) are subjected to unusual scrutiny (in an effort to eliminate fraudulent voters).
Consider some possibilities:
Obama wins, but there are challenges about those thousands of false registrations sponsored by ACORN, an organization he has worked with in the past and actually contracted with to foster voter registrations.
McCain wins, but there are complaints of "voter suppression" as election workers try to screen out the false voters represented by the bogus registrations.
It's a no-lose situation for ACORN, set up by themselves.
