Liberals consider Fox News a scourge, but what if it's doing them a favor? Harold Meyerson pens a letter to Fox News President Roger Ailes, thanking him for "reinforcing those beliefs that marginalize the Republican right." The network's focus on wedge and cultural issues increasingly appeals to the least-educated and -diverse wings of the party by painting "people who hold different viewpoints as alien and threatening," Meyerson writes. "In that sense, your work remains dangerous and disintegrative to the nation. But it is also, more narrowly, tactically, for now, a great gift to liberals and Democrats."
