HP on foreign policy
FF on domestic policy
Net FF, but Johnson really doesn't lend himself to this question format. Also, I always find it amusing how some of the people who hate Johnson the most for Vietnam are quick to rush to Kennedy's defense whenever the subject comes up.
What is amusing is that those who attempt to blame Kennedy do everything and anything possible to ignore that he had already begun the process of withdrawing troops from Vietnam (and state department documents have been revealed which show that he had given instructions to find a way to quietly pull out all the way), until Johnson reversed the policy. One can't blame someone for getting shot before he/she was able to finish carrying out his/her plan.
