"The Fact Checker started during the 2008 campaign and then went on hiatus for the first two years of President Obama’s presidency before becoming a permanent Washington Post feature in 2011..."
Was the hiatus because you didn't want to fact-check Obama?
We get to see 10 4-Pinocchio statements by Obama, in chronological order, but only beginning after the first 2 years.
The most-remembered one is: "If you like your health-care plan, you can keep it."
The one that relates to the tricking of Mitt Romney was: "The day after Benghazi happened, I acknowledged that this was an act of terrorism." What Obama had said the day after "Benghazi happened" was: "No acts of terror will ever shake the resolve of this great nation, alter that character, or eclipse the light of the values that we stand for."
That vague "no acts of terror" must have been carefully chosen, because he said it again, twice, the next day (with "act" instead of "acts"), "No act of terror will dim the light of the values that we proudly shine on the rest of the world," and "no act of terror will go unpunished." That states a general proposition without saying that Benghazi was an act of terror. And there is a distinction between "terror" and "terrorism" that Glenn Kessler (the Fact Checker) finds important.
