Howard Fineman writes this analysis in Huffington Post.

At the end, he itemizes the problems, but still fails to see something they have in common.

A roundup (edited for length):

ROMNEY STRATEGY. Last fall, as he was establishing the overall strategy for his campaign, Mitt Romney and his team were confident that the Obama presidency would collapse of its own weight; that the economic and job-performance numbers were so bad that the president was unelectable…They saw it as nothing more or less than a referendum on Obama’s (and the economy’s) record. They were wrong.

The mainstream media has not bothered to discuss Obama’s record. Fineman goes down an extensive list of what should have been problems for Obama. The media has given Obama a pass on all of them.

ROMNEY. Neither charismatic nor convincing, Romney has failed to establish himself as a credible, trusted vehicle for delivering attacks against the president…If voters are going to have to sacrifice — and they instinctively know that they do — it matters to them whether the new boss has a heart and a soul as well as a sharp pencil.

Romney has an extensive record of personal kindness and generosity, the kind of generosity that comes at his own expense and not that of taxpayers. The media has ignored it.

ROMNEY AGENDA. The GOP candidate’s action plan is so vague that it allows the president to be vague, too. And in many cases, Romney is poorly positioned to launch an attack, in part because of the radical anti-government stance he has adopted for this 2012 race. Rather than lean on the banks to write more mortgages, for example, Romney wants to lean on them less, for anything.

Romney has detailed plans available for anyone who bothers to look. The media spikes this as well. And just as an aside, “leaning on banks” is what got us into this economic mess in the first place.

DAVID AXELROD. The strategy of Obama’s message minister from the start has been to destroy Romney by any means necessary, and, with continuing help from Mitt himself, Axelrod has succeeded. Far from eschewing the politics of class resentment (a Clinton doctrine), Axelrod has embraced it with gusto, given the biography of his foe.

Axelrod is confident that anything he fires out there will be dutifully reported in the media exactly as he wants it to be. He is also confident that any mistake Romney makes will be a major issue, while Obama continues to “float.”

OBAMA…

Well, you get the idea. The media has circled the wagons so tightly around the president and other Democrats that there is barely room for air to pass through.  Meanwhile, they’re firing everything they’ve got against Romney and the Republicans, true or not.

It all boils down to the same thing. The “Fourth Branch of Government” is working for a single political party. People who dream of long-term single-party rule will think this is a feature, not a bug. The rest, not so much.
