"Krauthammer: 'Obama Clearly a Narcissist,' 'Lives In a Cocoon Surrounded By Sycophants'", Fox News 9/16/2014:
"This is all because, I mean, count the number of times he uses the word I in any speech, and compare that to any other president. Remember when he announced the killing of bin Laden? That speech I believe had 29 references to I – on my command, I ordered, as commander-in-chief, I was then told, I this. You’d think he’d pulled the trigger out there in Abbottabad. You know, this is a guy, you look at every one of his speeches, even the way he introduces high officials – I’d like to introduce my secretary of State. He once referred to ‘my intelligence community’. And in one speech, I no longer remember it, ‘my military’. For God’s sake, he talks like the emperor, Napoleon."
Since Krauthammer can't be bothered to check on mere matters of fact, I found the transcript of President Obama's speech about the death of Osama bin Laden, and checked the pronoun counts and rates. In fact, the speech contains 1396 words, of which 10 are 'I', for a rate of 0.7%. Perhaps Krauthammer was thinking of President Reagan's Address to the Nation on Events in Lebanon and Grenada, which did have "29 references to I" — though the overall word count was higher, so that the rate was exactly the same, at 0.7%.
It's a tribute to our nation's culture that a man like Krauthammer, who so consistently expresses blatant quantitative falsehoods about national leaders, is not only out of jail but comfortably established as a commentator for a major media outlet.
