It should surprise no one that the Associated Press, aka the Administration's Press, often first learns of stories when other outlets break them. When this occurs with a story about a Democratic Party politician in trouble, we get to see how the self-described "essential global news network" revises (i.e., cleans up) the outlet's original content to make it render as little damage as possible.
Today out of Nevada, there's the story of Steven Brooks, a State Assembly member from North Las Vegas. The Las Vegas Sun's coverage (HT Instapundit) opens with the following sentence: "A Democratic assemblyman is in jail, arrested for threatening Democratic Speaker-elect Marilyn Kirkpatrick, according to North Las Vegas Police and Democratic sources familiar with the situation." Since it concerns an intra-party squabble, tagging those involved as Democrats three times is not at all out of line -- in fact, it's necessary if one wishes to accurately communicate the situation.
