Republicans looking for a new leader have to look no further than Fox News head Roger Ailes, writes Newsweek's Howard Fineman this week. "Politics, like nature, abhors a vacuum—which is why God created Roger Ailes. The president of Fox News is, by default, the closest thing there is to a kingmaker in Anti-Obama America," Fineman writes. Fox has fueled the conservative populist revolt that is overtaking the party, Fineman says, and the channel will have a front-row seat at the Tea Party convention in Nashville next month. His station's recent acquisition of Sarah Palin gives "her a second tryout in the Bigs, while simultaneously using her to generate colossal ratings." Nothing could be more important in the party today.
