Is there another shakeup imminent at CNBC? Since the economy has been on the rocks, NBC Universal's financial network has been in the spotlight - political tug-of-war and all. This time, another one of the network's star on-air personalities, Jeff Macke, could be out.

Macke had been a cynical, sometimes conservative voice on CNBC's "Fast Money" and in other CNBC and MSNBC appearances, often pointing out flaws in the Democrat-controlled political culture in Washington, D.C. Now, he could be following the same path his former colleague Dylan Ratigan, who left CNBC's "Fast Money" in March.

Jon Najarian, a CNBC contributor and co-founder of predicted as much in a May 21 post on his Twitter site.

He's beloved by the gossip culture of Manhattan and was recently embraced by the left for hurling insults at CNBC "Mad Money" host Jim Cramer. But as Cramer's CNBC "Fast Money" colleagues explained, if you listened to NYU professor Nouriel Roubini, you would have missed out on a lot of stock market upside.

Roubini, often called Dr. Doom and known for crazy parties, predicted back in 2005 the speculative housing bubble would be the eventual undoing of the economy - and he was correct. However, as Jeff Macke, founder and president of Macke Asset Management and panelist on "Fast Money" explained May 11, being two years early with that prediction wasn't something to hang your hat on.

"Let me give you a little hint on trading," Macke said. "If you're two years early on any idea, what you are mostly is dead. You're a professor, as opposed to a trader. And if we still have time to talk after the five-minute butt kissing we gave the guy, I'll tell you what - he hasn't made anyone a cent. Until he does, as far as I'm concerned, it's a nice opinion but it's not making me money."

Want a little populist outrage?  There's nothing like hearing it from a multi-millionaire advertising mogul with a spot on CNBC.

Donny Deutsch, the host of "The Big Idea," a show the network has shelved, explained to viewers on the March 25 broadcast of "CNBC Reports" he wants measures put in place to keep prevent people he regards as "idiots" from making $10 million a year.

"The issue is even now, with the new asset program, basically if it works, the taxpayer's taking up all the risk," Deutsch said. "God forbid it doesn't work, taxpayers are really going to take it on the chin. And let's say we get it right and the banks are lending again and everything is fine again - what is now put in place on Wall Street to make sure idiots are not getting paid $10 million a year?"
