But the problem is not that journalists are trying to present both sides and be objective. The problem is they are NOT being objective. They are taking sides and their choices are based on political viewpoints and shallowly analyzed rhetoric instead of objective facts. When they take sides in a domestic election, we call it "politics". When they take sides in a war, it needs to be called "treason", and they need to be called "enemy".
It almost all comes down to three related things: Conservatives, Republicans, and Bush.
The people who make up the media, the vast majority of them, ae left wing, socialist leaning, liberals. Most editors, reporters, story writers, anchors, and producers see the world through a leftist perspective.
The opposite to this, of course, is the right. So, to the majority of people in the media, conservatives, republicans, right wingers, and the President are wrong on the issues. The people in the media disagree politically with them.
No matter what they say, this shows up in their reporting. They are biased because they think the positions of the right are wrong, and the positions of the left are correct. Some do try to check their impulses to let this worldview into their reporting, but most do not, and in fact don't even realize they're doing it.
The blatant partisanship brought upon this nation under the Clinton's and the Clinton's henchmen (Carville, Lanny Davis, Sid Blumenthal, Mandy Grunwald, etc) and the 24/7 cable news industry, with its constantly chattering debate shows, have conditioned the people in the media to make this partisan "edge" a flavor in their stories.
The Watergate victory of the left over Nixon has caused a whole generation of reporters to desire, more than anything, a similar sitiuation to happen to them, and elevate them to the percieved godlike position of Woodward and Bernstein, so there is a constant "gotcha" undertone to most political reporters today. Since their proclivity is toward the left, the favorite subject of "gotcha" politics is the Republicans. This is why most of Clinton's blatant scandals went underreported, and Bush's speck-in-the-eye incidents are dragged into the overreported spotlight.
This is never going to change as long as leftists continue to favor a journalistic career, or in other words, journalists naturally lean left.
