For me, the most fascinating presidential personality.
Epic FF for the passing of the Civil Rights and Voting Rights Act. He did what was right, even though he was fully aware it would harm irreparably his party. And I agree with Hillary on that: it's because of him, more than anybody else, that Barack Obama sits in the Oval Office as we speak.
He botched Vietnam of course. But then again as one of my compatriots said ''Little men make little mistakes. Big men make big mistakes''.
P.S. Forgot to add the poll.
The Great Society was both visionary and morally correct. His stance on Civil Rights was courageous and prescient. Vietnam, though its roots are traced back as far as Eisenhower, can be lain on one of Lyndon's shoulders and one of Dick Nixon's. It was a crime against humanity, regardless of how well intentioned many of its participants were.
Your use of the term "fascinating Presidential personality" couldn't be more correct, Pbx. I am hard pressed to think of a more colorful President. Uncouth and foul-mouthed one minute, genteel and persuasive the next. I suspect no President would have been more interesting to watch (as a "fly on the wall") than LBJ. I love how other pols describe getting "the treatment"....
