It has been a busy few days for PolitiFact and the Truth-O-Meter.
On Sunday, Daily Show host Jon Stewart ventured into enemy territory when he was interviewed on Fox News Sunday by Chris Wallace.
Stewart often targets Fox with his satire, so the interview was contentious.
At one point, Wallace defended his network by saying Fox viewers got more balanced coverage because it came from "somebody who tells the other side of the story."
Stewart said the network's viewers were getting political spin, not facts.
"Who are the most consistently misinformed media viewers? The most consistently misinformed? Fox, Fox viewers, consistently, every poll," Stewart said.
On Monday, at the suggestion of many readers, PolitiFact put that to the Truth-O-Meter. PolitiFact writer Lou Jacobson found several polls that assessed whether viewers of Fox were well-informed and discovered that while Fox viewers as a whole were sometimes near the low end for their political knowledge, they were not consistently the lowest as Stewart claimed. PolitiFact rated Stewart's claim False.
On Tuesday night, Stewart responded on the Daily Show and acknowledged PolitiFact's ruling. "I defer to their judgment and apologize for my mistake. To not do so would be irresponsible."
He then read a series of claims from people on Fox that had been rated False by PolitiFact. The claims filled up the left side of the screen and then the right side until they covered the entire screen. Stewart indicated he was getting weary of reading the lengthy list and began munching on trail mix to regain his energy.
"Well, I'll tell you what," he said. "They've got a lot of (expletive deleted) correcting to do."
