All the discontent is generic with no specifics at all.
Of course, that did not stop the media from misrepresenting the polls. The agenda first, you know.
Heck I'll bet on election day 2004 Bush would have lost to a generic Democrat. He just wasn't going to lose to the specific one on the ballot namely Kerry.
Without knowing what the normal percent is that's meaningless. Maybe it's usually 80 or 90 percent. That sounds like a low number to me but I'm just guessing.
