There’s nothing strange or mysterious, Victor, about President Obama’s political assualts on Sean Hannity, Rush Limbaugh, and other radio voices on the Right. The administration hopes that it can convince the public that these guys are the leaders of the GOP at the moment. Since these guys are thought to be relatively unpopular with non-movement Americans, this holds all sorts of political promise.
Bill Clinton did the same thing in the 1990s by tying the GOP to Newt Gingrich and thereby reviving his political fortunes after the 1994 mid-term debacle. And since the GOP seems more than happy to cede political and intellectual leadership to the likes of Hannity and Limbaugh, it may well prove as politically useful now as it did then.
