We are at war. The troops put their lives on the line for us. Which candidate will better support the troops that support us? Hillary, Obama, or McCain?
Your point is one that must be considered seriously. A rational person must view his or her actions with the constant knowledge of the fact that we indeed are at war.
As a former supporter of Senator McCain (I am shamed that I helped elect him to the Senate) I wish to offer my thinking on this subject.
Senator McCain is irrationally angry. He doesn't just have a temper problem, he lives as a temper tantrum. His abuse of people who have only slightly irritated him is a matter of the public record, is consistent, and has always been repugnantly extreme.
Angry people, especially ones with as chronic a temper as Senator McCain, are simply irrational in the fit of their anger. Their judgment is absent. It is one reason we have recognized the irrational aspect of behaviour committed in anger in our own laws - see "fighting words" and the concept of "crimes of passion".
The fact that angry people are by nature non compos mentis is beyond dispute. Those therefore with a consistent and persistent temper problem are subject to simply being insane/irrational a great portion of their waking hours.
Senator McCain is a greater danger to our safety and security, strangely, than either of the Dems. I am convinced that he is incapable of "putting a sock in it" and is enormously likely to cost us a hideous butcher's bill due to his irrational temper tantrums.
Therefore I'm sorry, I do not find your defense to be as persuasive as you may have expected.
I wish everyone would read your post. It is the most important post on this thread.
