Kos has been wishing for Hackett's demise from the beginning. He fervently hoped that Hackett would drop out.
For example:

If Sherrod Brown loses, we the netroots will rightfully blame Kos for the failure of winning DeWine's seat. Today, I am ashamed how a cabal of bloggers-Kos and Jerome helped to end a bold and courageous person, Hackett's run for political office. He would have been a person of integrity and dignity.
We the netroots will remember this day of infamy. I am sorely disappointed by the backstabbing action of kos and jerome against Hackett. At least Atrios was neutral in this race.
Hackett, we still love you. Do not let a bunch of backstabbers take your will away. Rise up and fight. Don't let them keep you down!!
