Sorry, but there are two great homonyms in this fine post. They definitely fit the theory that words in Yglesias's mind slip out his fingers when he would have rather typed a different word which sounds the same. T
Barack Obama's first book Dreams From My Father: A Story of Race and Inheritance [snip]
It's a pretty impressive achievement and also probably helps give him some of his heir of authenticity. One knows that he know more writes his own lines at this point than does any other major presidential candidate, but he seems like someone who could.
So even when miss typing, Yglesias knows that the h in heir is silent so it sounds like "air". He typed it by mistake when writing about Obama's inheritance of dreams. Then he knows how to spell know but with "to know" still in his mind from 3 words ago, he typed know.
Nice. Too nice. I suspect he is doing it as a joke.
