Best president of my lifetime: Lyndon Johnson, notwithstanding his atrocious blunders in Vietnam. He pushed through the Congress the most important civil rights legislation since the end of the Civil War. I am not sure whether he or his predecessor, Kennedy, was responsible for Medicare and/or Medicaid.
Worst: Easily, Tricky Dick, notwithstanding his opening to China. If any other person had done with China what Tricky Dick did, Tricky Dick would have been his leading critic. But his Watergate crimes wipe out any credit he gets for doing anything right (which was not that much, anyway).
Special note to Joseph: I can’t tell you why anybody else used initials like FDR, HST, DDE, JFK, LBJ, RMN, GRF, GWB, GHWB, RWR or JEC, but with me it would be because I am lazy. Use of initials does not constitute an honor or expression of admiration, whether the writer is liberal, conservative, smart or stupid. And while you are at it, study the difference between initials and acronyms. Here’s some help: When GRF passed out WIN buttons, he was using an acronym for Whip Inflation Now. But the ACA (Affordable Care Act) is just a bunch of initials, not a bunch of initials that make a word that people can use.
