Many people think that McCain's POW status is something that we shouldn't mention. However I think it is the opposite. We should be constantly mentioning it and we should be trying to get McCain to constantly mention it?
Why? Because people want more than someone who was a POW 30 years ago as president. If McCain is talking about his pow status while Obama is talking about new energy solutions that is a win for us.
McCain's pow status is like Obama's position on Iraq both were respected deeds, but we know that about you we want to hear more.
Pointing out that McCain's pow status has given him too big a temper, health problems, and etc I think would be good. Why? Because they are true. The goal being to point out that there are negatives to McCain's POW status as well as positives and that that is all there is to McCain.
Right now people are cheering the cross in the ground story despite its questionable veracity. However after they hear it 30 times it will lose its emotional impact.
