Leftists Out-Of-Sync With Reality?

In the Wall Street Journal, John Steele Gordon writes about how history is pulling away from traditional leftist paradigms:

Valerie Jarrett, senior adviser to President Barack Obama, recently explained the White House war on Fox News as an example of "speaking truth to power." Much of the American political world collapsed in laughter, pointing out that her boss was president of the United States, the most powerful man on earth. His every word is news around the world. Fox News is a cable channel rarely watched by more than a few million people at a time. How could she have so blithely said something completely out-of-sync with reality?

Simple: She's a liberal.
