I was rummaging through the boxes of books in a local thrift store and found a 1964 book entitled A Texan Looks at Lyndon: A Study in Illegitimate Power by J. Evertts Haley published by a press I never heard of before, The Palo Duro Press of Canyon, Texas. Well, this instantly smacked of presidential political attacks - it was published in an election year, coincidence? No chance!
and I am wondering what the earliest example of this sort of 'expose' during a campaign is. John Adams? Does anyone have a clue?
