Here's a couple of clips showing some recent anchor squabbles during MSNBC's coverage of the DNC this week.

In the first, Keith Olbermann challenges Joe Scarborough on his contention that John McCain's campaign has made strides against Obama. In the second clip, Scarborough loses it when correspondent David Shuster refers to the Republican party as his party -- even though the MSNBC host was a GOP congressman elected from Pensacola amid Newt Gingrich's Republican revolution.

Variety cited these clips as evidence that Scarborough may be getting tired of the increasingly left-leaning MSNBC. But they're ignoring another clip where Olbermann also groused about Chris Matthews' tendency to, um, dominate the conversation.

It all reminded me of a conversation I had with a manager at a big media outlet about a star who once worked for him. He said the star was most dangerous when he was doing well, because his ego got so huge, no one could stop him from saying and doing things to alienate people.

Looks like Olbermann may be headed toward that cliff. Again.

Judge for yourself:
