In the Wall Street Journal Fred Barnes writes that Of course journalists point to the many times they've taken on liberal politicians, especially Speaker Pelosi and Senate Majority Leader Harry Reid and, at times, Sen. Obama. But their criticism is of a special type. They point out political mistakes, clumsy tactics, bad decisions on timing and process failures. They don't raise doubts about liberalism itself or the liberal agenda. Conservatives aren't so fortunate. The media challenges their basic principles.
