I want to be clear. I don't consider being wrong -- either by mere gaffe or by some form of ignorance -- the same as lying. The difference, when it comes to political and other leaders, is that lies are told to advance some end and in response to being called on them, they try to dance and wiggle their way out of them or they double down on them. When such people are just wrong with no malfeasant, conniving or contriving intent, they just own it and move on. Everyone knows this just as well as I do.
Now here's the thing. Even though everyone is at times honestly mistaken/wrong, there are some things people in the White House just aren't allowed to be wrong about. The fact is that being privileged to serve the U.S. from the WH carries with it a higher bar. The electorate, other nations and their leaders, the press, and everyone else must be able to rely on the veracity of what a President and his Administration employees say.
The problem with Trump and his Administration isn't they are the intellectual equivalent of Gerald Ford and his physical clumsiness, it's that they are found with regularity to be be wrong, and for many of the misstatements there is a clear political end being served by the misstatement, paltering and prevarication. That's the problem, not that folks merely slip up by saying "Korea" instead of "Crimea," or "Atlanta" instead of (perhaps) "Orlando."
I kind of see the Korea-Crimea gaffe. It's harder for me to "get" the Atlanta-Orlando thing, in large part because (1) not only are the two city names not at all similar, but also (2) he said it three times in mere minutes. That said, Spicer did say he meant Orlando. Okay. I'll give him a pass for it.
