The interesting thing here: who does he think he's talking to?The @WashingtonPost quickly put together a hit job book on me- comprised of copies of some of their inaccurate stories. Don't buy, boring!— Donald J. Trump (@realDonaldTrump) August 23, 2016
The audience for Trump's tweets is not yours truly (who mines them for comedy and cognitive dissonance). The audience for Trump's tweets would never consider buying a book (probably) about their beloved icon that was written by two reporters for the Washington Post (certainly).
And the audience for that book will never read Trump's Twitter feed, and certainly wouldn't take advice from the man if they saw this tweet elsewhere (like, here, for instance).
So what is the point of this tweet, other than petulance and egomania? I mean, seriously: people are worried about donations to a charity run by the Clintons when this clown wants to be President and represents the other major political party in the country?
