That's my favourite one. They've also put forward the theory that Rove sabotaged Weasley Clark's primary campaign as well.
Idiot DU'er: "And just how did Rove sabotage Dean, because you can't rig a caucus."
Idiot DU'er deux: "Oh yes you can. You can pretend to be from the Dean campaign, and then call all his supporters in the middle of the night, waking them up and making them mad. Then they won't show up for you. You can force all the editorial boards to endorse Kerry. You can blackmail the Governors wife into endorsing Kerry."
