1. The poll was conducted by CBS News
2. CBS News
3. I think CBS would not have a direct interest in whether or not gays can or cannot serve in the military, I believe that some of their readers might be interested. CBS is a news company, so it is their job to give up to date information on topics that may affect its readers. I don't know whether or not CBS has any type of political affiliation, but politics are one of the most popular news topics, so it seems very likely that many watchers of CBS news would follow politics. The topic of "Don't ask don't tell," was one of many questions from the survey that involved politics and the Obama administration. The poll also gave information about the way members of the party responded, so I think this poll was set up to show the different views of people with different political affiliations.
4. The methodology was, "a random sample of 1,067 adults nationwide, interviewed by telephone November 29 - December 3, 2010. Phone numbers were dialed from RDD samples of both standard land-lines and cell phones."
5. The poll results are laid out in a pie chart and in three categories: favor which includes strongly favor and favor not so strongly; oppose which includes strong oppose and oppose changing the law but not so strongly; and the last section was I don't know. The article gives the percentage of both the answers that make up Favor and Oppose. It also outlines how members of a political party responded to the questions. Also, the article linked the results of the entire poll here.
6. The graphs are used in a somewhat clear and informative matter, however they can be misleading since both the favor and oppose sections can be broken down into more categories.
