Fox Nation, please define “record low”

I don't think “record low” means what Fox Nation thinks it means.

When you click through, you eventually get to this Rasmussen story, which says absolutely nothing even remotely like “Obama sinks to record low approval.” And if you poke around on Rasmussen's site, you find that according to Rasmussen, Obama's approval rating is the highest it has been in nearly two weeks.

My understanding is that “record low” means “the lowest ever.” What does Fox think it means?
