The MSNBC coverage of the Democrat National Convention was totally slanted, and nothing short of an outright commercial for the Obama/Biden ticket. Besides having their Obama Love-In, the anchors at MSNBC displayed their disdain for each other. Check out the Olbermann Watch.ANIMOSITY among MSNBC anchors has reached a mile-high peak at the Democratic National Convention in Denver, with on-air squabbling between such big egos as Joe Scarborough, Keith Olbermann, Chris Matthews and David Shuster.Scarborough, who served in Congress as a Republican representative from Florida, seems to be particularly touchy being the only host who isn't openly pro-Democratic.Yesterday, after Shuster referred to "your party, the Republican Party," Scarborough went off, sparking a seven-minute exchange."I will let you know that 'my party,' my party loathes me much more than your party, the Democratic Party, loathes me," Scarborough seethed. "What about your party? What's your party, David Shuster? David, what's your party?""I have no party. I'm a complete independent," Shuster replied."Oh, I feel so comforted by the fact that you're independent. I bet everyone at MSNBC has 'independent' on their voting cards," said Scarborough.Scarborough declined to talk to Page Six, but sources say he and NBC anchor Tom Brokaw disagree with MSNBC's decision to position itself as the channel for George W. Bush-haters.At a forum on Sunday, when Pennsylvania Gov. Ed Rendell called MSNBC "the official network of the Obama campaign," Brokaw said, "I think Keith has gone too far. I think Chris has gone too far."Insiders say Olbermann is pushing to have Brokaw banned from the network and is also refusing to have centrist Time magazine columnist Mike Murphy on his show."The idea of anyone trying to ban Tom Brokaw is ludicrous," said one MSNBC-er. Brokaw was on MSNBC for an hour yesterday afternoon. Murphy, who was bumped from Olbermann's show on Monday night, told us, "They told me technical problems and I have no reason not to believe them."more abo
