IT’S CALLED JOURNALISM:  Politico’s Bill Scher seems truly baffled by Fox News’ hosts/reporters who ask tough questions of GOP presidential candidates: “Fox News Eats Its Own.’  Yes, that’s what actual journalists do: They ask tough questions, and they don’t “play favorites.”  Shocking, I know, to a liberal/progressive mainstream media that hires hacks parading as hosts, such as George Stephanopoulos, Dan Rather, Candy Crowley and Keith Olbermann.
