Yes, that's the general way that the judicial ethics rule is stated. But Ms. Taitz was possibly thinking of the (proverbial) unseen 800 pound gorilla in the room: Obama's FCC, which could possibly harm Comcast (and any shareholder's interest in it) in retaliation if Judge Land didn't dismiss her case against Obama quickly. This administration is capable of things more vindictive than that - it's called "the Chicago way."
By that reasoning, every judge in America is disqualified, because there is theoretically something Obama could do to any of them.
Sorry, if you are going to move to disqualify a judge, you'd better have the law on your side.
