Fifty years ago today, on October 27, 1964, Ronald Reagan delivered his (in)famous "A Time for Choosing Speech" in support of Republican Presidential nominee Barry Goldwater over President Lyndon Johnson. Soon thereafter, LBJ went on to defeat Goldwater in one of the greatest landslides in U.S. history. So, in that respect at least, Reagan's speech wasn't toxic. But in most other respects, the speech — and Reagan himself — were a dangerous mix of dishonesty, demagoguery, delusion, and divisiveness.
