The following presentation styles were gleaned from an observation of right-wing broadcast media over the months leading up to the 2004 election. (The principle sources were right-wing radio, the Drudge Report and Fox News web sites, and Fox News Channel.)
(For copyright issue, I'll use list their list, but they do expand each point)
1. Highlight a quote from the opponent out of context from a speech or interview.
2. Use loaded terminology to describe a disliked program.
3. While attacking liberals, promote the idea that it is conservatives who are under attack or marginalized, whether you actually are or not.
4. Give coverage--and thus credibility---to right-wing groups and individuals with an overtly biased perspective, while granting some limited coverage to the liberal opposition.
5. Attack people and their credibility, making them rather than the issue the focal point of discussion.
6. Find some vulnerability in the opponent and make that the focus for evaluating him or her.
7. To divert attention away from a liberal opponent's attack on a conservative position or individual, discredit widely one piece of their argument as a way of discrediting their entire argument.
8. Accuse the opposition of doing the same underhanded things to you that you yourself refuse to acknowledge doing to them.
