Why won't Wolf Blitzer do his job?

I was watching Wolf Blitzer on Sunday, and he had Dan Bartlett the WH guy on.
Now please tell me why Mr. Bartlett was allowed to state pure WH talking points without Wolf once challenging him?

Either Wolf doesn't know the facts, in which case he's not doing his job,
or he does know the facts, and he allowed Mr. Bartlett to mislead the viewers
with no clarification/correction.

Either case is unacceptable.

Now multiply that by the number of times CNN and CNN Headline News repeat what are basically WH talking points (in tiny little bites with little to no context)...

You could also multiply that by all the other channels and news outlets that do the same thing daily.

What I'm getting at is why even bother to pretend to call it "news"?

As far as Wolf Blitzer goes, he can't ask the tough questions every once in a while, he's responsible for what the viewer takes away from every show.

I'm always afraid that a considerable percentage of the viewers aren't informed enough to know how to tell the spin from the facts, and if the difference isn't made clear at that time by [people like] Wolf then the viewer could be left believing statements that are untrue (aka lies).

And really that's what is happening all the time. The people we should be able to trust to weed out the spin from the facts are letting the American people down on a daily basis!

Another of the things that really burns my ass is the veteran political reporters who see political dirty tricks and all the crap that goes on as 'tradition' and sometimes talk about it in a semi-romantic way.
Things they should be condemning, not brushing it off as 'business as usual'.
