The media might not be overly concerned with presumptive Democrat presidential nominee Barack Obama's incessant campaign flip-flops, but the leader of the Netroots, Daily Kos proprietor Markos Moulitsas, is so disturbed by the junior senator's recent changes of heart that he has decided to hold back his financial contribution (file photo).

As NewsBusters has been reporting the past few weeks, this disillusionment with Obama from the ultra-left has been quite vocal of late, and growing.

However, such publicly expressed disheartenment from someone like Moulitsas, coming just weeks after Hillary Clinton's concession, could be quite a problem for the Democrat candidate that media seem to be ignoring; a Google news search identified very little coverage of Kos's 2:05PM post on Tuesday (emphasis added, h/t Hot Air):

So many of you are upset that I pulled back my credit card last night, making a last minute decision to hold back on a $2,300 contribution to Obama. [...]

First, he reversed course and capitulated on FISA, not just turning back on the Constitution, but on the whole concept of "leadership". Personally, I like to see presidents who 1) lead, and 2) uphold their promises to protect the Constitution.

Then, he took his not-so-veiled swipe at MoveOn in his "patriotism" speech.

Finally, he reinforced right-wing and media talking points that Wes Clark had somehow impugned McCain's military service when, in reality, Clark had done no such thing. [...]

Maybe what looks like cowering to me is really part of that "moving to the center" stuff everyone keeps talking about. But there is a line between "moving to the center" and stabbing your allies in the back out of fear of being criticized. And, of late, he's been doing a lot of unecessary stabbing, betraying his claims of being a new kind of politician. Not that I ever bought it, but Obama is now clearly not looking much different than every other Democratic politician who has ever turned his or her back on the base in order to prove centrist bona fides. [...]

Ultimately, he's currently saying that he doesn't need people like me to win this thing, and he's right. He doesn't. If they've got polling or whatnot that says that this is his best path to victory, so much the better. I want him to win big. But when the Obama campaign makes those calculations, they have to realize that they're going to necessarily lose some intensity of support. It's not all upside. And for me, that is reflected in a lack of interest in making that contribution. [...]

And if for some crazy hard-to-see reason my money actually is important to the Obama campaign, then they can adjust their behavior to get it.

Powerful stuff even though it went largely unnoticed by most press outlets from what I can tell: a Google news search identified that amongst major media, only the Washington Times and the New York Times reported Moulitsas's announcement. There may have been more, but LexisNexis is currently unavailable.

On the other hand, Huffington Post contributor Allison Kilkenny was all over this story moments after Kos pushed submit (emphasis added):

Ideological contortionist, Barack Obama, marches toward his personal goal of causing one million progressives' heads to simultaneously explode.

He obtained an essential first step toward this aim when he capitulated on FISA, a move so contradictory to the core of the Progressive movement that outraged midget, Markos "Dailykos" Moulitsas, yanked a generous contribution from Obama's bony fingers as punishment for the sneaky, immoral maneuver. Moveon.org was also unhappy with Obama, all of which brings to mind the ancient expression: If You Wrong The Progressives, Protect Your Crotch.

These burns aren't going to heal any time soon. John Kerry turned out to be an empty shell of a candidate, but Barack Obama had real potential, or so the Progressives thought. They sunk their time and money into Obama, and as thanks, he turned around and bit the hands that fed him. [...]

Of course, the motivation of his pissed-off base was supposed to have been what was going to keep Obama on track in the first place. With that not working, progressives have few options left, and their trust is waning in the last great savior for the so-called progressive movement.

Also powerful stuff, and seemingly important -- except to most media members.

After all, Kos could be right, and Obama might win without the support of the Netroots and their followers. However, that only seems likely if Obama-loving press outlets continue to ignore the junior senator's flip-flops -- or call them good political decisions -- and fail to report growing disdain for his changes of heart within his very base.

Can they do this for another four months? Stay tuned.
