Regularly, Instapundit — rightly — reminds its readers of the definition of modern journalism according to Jim Treacher and to Iowahawk. Both definitions are outstanding, but I think there is room for an additional one.
Here, then, are:
The Two Rules of Modern Journalism
RULE # 1: Journalists are required to be open-minded, exercise independence of spirit, and display a healthy amount of skepticism. Therefore, people, famous and non-famous alike, being interviewed (on the TV studio set or elsewhere) must be treated with a degree of skepticism and constantly be questioned, second-guessed, doubted, fact-checked, challenged, and, more often than not, interrupted (more or less politely).
RULE # 2: Rule # 1 only applies to Republicans.
(And to anybody leaning conservative.)
For Democrats and leftists, the main type of query is more along the lines of "pray enlighten us to your glorious plans for fundamentally transforming America (we will be quiet now)." (Close second: "kindly tell us how much people have suffered, and are still suffering, in this dreadful country of ours.")
