Here's an example of why a lot of us lost the positive feelings we once had about John McCain. An interviewer asks him if it's true that the use of contraceptives helps stop the spread of HIV. There are twelve year olds in this country who could have told you they do. I would even have respected an answer that admitted it's so but wondered if the availability of condoms made people more likely to engage in sexual relations. I think that's nonsense but it's an aspect of the matter that's worth considering.
Instead, McCain dodges the question.
