Wonkette reports the hacker group claims to have infiltrated the GOP's top-secret ORCA computer system. The Romney campaign says ORCA was a system to help them get out the vote, but Anonymous says it was actually an effort to manipulate vote totals. In a letter the group writes:
"We began following the digital traffic of one Karl Rove, a disrespecter of the Rule Of Law, knowing that he claimed to be a Kingmaker...
"After a rather short time, we identified the digital structure of Karl's operation and even that of his ORCA. This was an easy task in that barn doors were left open and the wind swept us inside.
"We coded and created , what we call, The Great Oz. A targeted password protected firewall that we tested and refined over the past weeks. We placed this code on more than one of the digital tunnels and their destinations that Karl's not so smart worker bees planned to use on election night."
The group says they were able to lock Rove and his "worker bees" out of the ORCA system on election day.

Here's a pre-election video from Anonymous warning Karl Rove to not try any funny business:


This is so obviously true, yet nobody wants to believe it: the same thing happened in 2000 and 2004 but nobody wanted to believe it then, either.
One thing's for sure: they are not getting away with it this time, Anonymous has made that plain.
