Grazing through LGM I come upon this post, whose first link leads me to this page from a Politico article, where I see this:
Boot continued to provide POLITICO with email correspondence between he [sic] and Rosen and he [sic] and Roberts throughout the day on Friday.You don't have to know the rules of English grammar -- "between" is a preposition and therefore takes the object "him," not the noun "he" -- to know that "between he and Rosen" is wrong. It sounds wrong. Someone who has never cracked an English grammar text and whose native language is English should be able to write reasonably correct English if he or she has a reasonably good ear.
So, all together now: "Between he and Rosen" is wrong. "Between he and I" is also wrong. "Between you and I" is also wrong. Thank you. Jesus ******* *****.
Added later: Technically, it should be "the first link in which," not "whose first link." But some rules can be broken. Other rules should never be broken. The way to tell the difference is to listen.
