You're doing everything you can to avoid trying to show they're not.
It's your claim that they're not. If you don't want to stand behind it, that's fine.
No, it's your claim that they are. Disproving a claim that YOU made requires work. You are effectively giving me a job to do on your behalf. You have no responsibility other than sending me on a wild goose chase.
I can give you a quick run down on some of them:
Fareed Zakaria - Generally a Reagan-type in ideology, believes in the faux-meritocracy, supported the Iraq War, frequently lectures the left on why their ideas are wrong.
Erin Burnett - Works for a neoliberal and neoconservative think tank, disparraged and mocked the Occupy Wall Street movement
Christine Romans - Lou Dobbs protege who helped spread his racist conspiracies while on CNN. Why is she still employed?
Dana Bash - Celebrates moderates, calls moderates the 'badasses of congress', credits the impeachment movement to moderates
Smerconish - Admits to being a Bush era moderate independent, promotes libertarian candidates and centrism
Jake Tapper - Has tweeted the 'Millennial Socialists' are coming; considers himself a moderate independent
Wolf Blitzer - Before he was a journalist, he promoted anti-Palestinian, right-wing Israeli talking points
Cuomo - Centrist / Moderate, thinks the Democrats have a leftist problem; thinks that Bernie is extreme.
Now that I've done this much work, you don't really have to do anything, right? That's why I don't like getting sucked into these phony challenges without the challenger putting skin in the game.
