Ed Schultz is the kind of shameless liberal hack who can go on air standing in front of screaming labor-union crowds in Madison, Wisc., calling for Gov. Scott Walker's head on a platter, and then turn around and announce that "Fox News is an arm of the Republican Party."

Let's put this canard to rest. In coverage of the leftist effort to drain the taxpayers of Wisconsin for an unnecessary and doomed recall election, Fox looks much more objective than Ed Schultz. There is no question about that.

A new Media Research Center study shows "The Ed Show" guest count tilted against Walker by 237 to 1. Think about this. One person supports Walker, 237 against him. Contrast this with "The O'Reilly Factor's" guest count on the subject: 12 guests for Walker, eight opposed, seven neutral.

This is really only a fraction of Schultz's full-throated advocacy of the Wisconsin union agenda. After all, he blasts away on the radio for three hours a day. It's his right to advocate — but not to participate in character assassination. Both on radio and on TV, Schultz asserts that anyone who votes for Walker "may be voting for a criminal." Prosecutors are investigating potential campaign improprieties while Walker was Milwaukee County executive, but let's be clear: Walker has in no way been implicated in the scandal. Schultz is slandering.

Of course, Schultz is not alone. The national news media trashed Gov. Walker in 2011 for getting a bill passed that forced public-employee unions to make a modest payment toward their own health insurance and pension plans instead of having the overtaxed public foot the entire bill. Union protests against this proposal were compared to the Arab Spring. "Cairo moved to Madison," cooed Diane Sawyer. The New York Times suggested Wisconsin was "the Tunisia of collective bargaining rights."

I could state that the unions are behaving like Gestapo thugs — but that would be uncivil wouldn't it?

But the bill became law, and how has the Badger State fared? The Weekly Standard humbly asked Walker's challenger Tom Barrett — the same guy Walker defeated in 2010 — for specifics on which school districts were harmed by Walker's policies. Barrett couldn't name a single one. He babbled about his discussions with prison guards and couldn't provide any specifics at all. And they said Sarah Palin wasn't ready for the spotlight.

Now that Wisconsin isn't collapsing, and in fact is seeing a dramatic economic improvement, it's somehow no longer Hosni Mubarak's Egypt, and the liberal networks have pretty much stayed away. But Schultz keeps pounding away in a panic, lamenting that not only is Walker "the worst governor in the country," but that those evil Republicans and their capitalist funders, like the Koch brothers, are "trying to make it so Barack Obama doesn't get re-elected and no Democrat ever will be elected into the White House." Schultz warned, "There'll never be a Democratic president in our lifetime again. And when I say in our lifetime, I'm talking about a long, long, long, long, long time."

Scare tactics, anyone? This guy is to talk radio what the Bill Moyers "daisy ad" was to political advertising.
