Stephen, you're missing the point: there's a difference between misspeaking and lying.
For Matalin and Rudy to lie about things they knew directly about (and which seem to be the new talking points of the right) is completely different from casual misstatements about "57 states" or TV vs. radio which aren't part of some larger plan to deceive.
So, back to my question: you think Biden purposefully lied? Did FDR not use the mass media to calm the country during crises in the Depression? If he didn't, that might be a lie; if he did, it's an inconsequential misstatement.
OTOH, Matalin and Rudy trying to obfuscate the domestic security blunders of the last Administration in their efforts to tear down this one are orchestrated lies.
In fact, they are such Big Lies that they are eligible for the "Josef Goebbels Hall of Shame."
