I said "all of the veterans who signed on the dotted line for over 20 years of service". There is something called a "phrase" after the "all of the veterans" part. Phrases cannot be ignored without changing the meaning of that which they modify. In this case "who signed on the dotted line for over 20 years of service" is modifying "all of the veterans". In other words, that in no way says the same thing as "ALL Vets". Your understanding of "imply" is lacking, too. I never said NOR implied that they won't VOTE for W. I said that they were pissed off. Pissed off as they are, they may or may not vote for W. Pissed off is NOT the definition of "won't vote for". Either way, they got screwed.
You must have gone to public school. Here's some help, though: How to Diagram Sentences.
So, I agree that some veterans are pissed at government in general and because of that Bush as its head. I agree that some of these angry veterans may have hoped that Bush would have changed the situation and are angry that he isn't. I disagree that the author has the ability to imply that the majority are angry and of that majority the majority have changed their support for Bush.
