I don't think so. Consider the alternatives and wording. FR is without a doubt more trustworthy that Fox, CNN, ABC et al., and Drudge. Those who picked one of the others may not have experienced FR.
The use of "none" for the final choice leads people to pick the most trusted of the choices given, not that most trusted of all. If the final choice were "Other", than the results may be different.
Me knoweth this poll got freeped.
