The exact same thing is happening to "The New Adventures of Old Christine". The last few episodes of "Rules of Engagement" have the same number of "abysmal" votes as the last several episodes of "Old Christine", so it's obvious that there is voting sabotage going on. Someone at the "Old Christine" board thought that mabye fans of "Rules of Engagement" were sabotaging the votes, but the same thing is happening here.
How stupid can people be to deliberately sabotage a show's ratings at tv.com? I mean really, don't they have better ways to spend their time?
