A recent study by Harvard, hardly a bastion of consevatism, finds that the MSM is biased against Republicans. More articles are written about Democrats and the tone is usually positive. Fewer articles are about Republicans and the tone is usually negative. Here is the link to an article about the study with the statistics:

Many writers are simply one track. In the Ft. Worth Star-Telegram editorial writers like Joe Galloway and the late Molly Ivins have a simple theme; Democrats are good, Republicans are bad. There is really no reason to waste your time reading the articles. It reminds me of a Calvin Coolidge story. (President Coolidge was a man of few words.) Once, as he left church, a reporter asked him what the day's sermon was about. Coolidge said, "Sin." The reporter asked what was the preacher's message? Coolidge said, "He was against it." That pretty well summarizes most church services.
