It looks like the heightening divisions with the Democratic party over the Obama-Clinton contest are causing an open split in the online progressive city known as DailyKos.

Judging the efficacy of a Google bomb campaign against John McCain; three liberal blogs ask readers if they should endorse a candidate before the nominee emerges; another piece about why Twitter matters; illustrating the strength of viral video; congrats to Josh Marshall on his Polk Award and NYT profile; Hillary Clinton launches Delegate Hub, controls the tubes; John McCain continuing to generate little online enthusiasm.

As Congress considers again a new FISA update, bloggers urge Barack Obama and Hillary Clinton to head back to Washington for the vote; a CREDO campaign to get voters to email Obama and Clinton about the vote allegedly causes Obama's email server to crash; new charts from Matthew Hurst show online buzz for the Republicans and Democrats; more Fred Thompson post-mortems, and a question about why he failed to use the web as promised; EveryBlock is a great new site that helps you find info about your city block; Clinton Internet Director Peter Daou tries out some spin on DailyKos, gets walloped; and two sites compare the candidates' stances on tech and science issues.

Mitt Romney wins Michigan, and the war metaphors get upped a notch; it's not quite clear if Markos had any effect on the primary, and a CNN poll suggests most Dem votes went to McCain; Richard Viguerie launches a pro-Ron Paul site, harvests email addresses; Sarah Lai Stirland on the teenage forces behind Hucksarmy.com; Slashdot is conducting a reader-generated interview with the candidates; and beware: General Zod is runing for president, and will make you kneeeeel at his feet.

We already know that most presidential candidate websites are notoriously bereft of in-depth information about the candidates, other than a few hand-picked issue memos and the usual biographical fluffery. But we didn't know until today just how poorly these sites do in attracting attention from the most active denizens of the political web.

The FEC recommends that John Edwards not receive matching funds for the $4.3 million he raised on ActBlue, and DailyKos protests; a single Republican activist has a list of 71 million Christian voters, prompting the left to grasp for their own; Craig Newmark co-hosts an Obama fundraiser; Glamour magazine launches a group blog about the race; Barack Obama ba-reaks the 200,000 MySpace barrier; Chris Dodd speaks at Google, asks them to write his tech policy; and Matt Lewis says negative blogging is just hitting its stride.

Markos Moulitsas covers the campaign for Newsweek -- who will be his counterpoint?; asking political reporters to move beyond the horserace; Meetup plans a super-top-secret project; TinyURL supporters Ron Paul, web addresses stay long; Republicans are behind a new anti-Hillary Facebook group; is Hillary dissing the youth?; and your friends at techPresident are featured on Rocketboom.

The New Hampshire blog Blue Hampshire gets a profile in the Wall Street Journal; Why Tuesday gets responses about election reform from 11 out of 16 candidates; two conservative bloggers filed an FEC complaint against Hillary Clinton; are Ron Paul supporters using botnets to send out thousands of spam emails?; Joe Trippi and Cyrus Krohn, mano-a-mano; Ed Markey taps the opinions of DailyKos readers; and Stephen Colbert's Facebook group is generated an uptick in registered voters.

Slate writers on the glories of Google Suggest; James Kotecki officially joins the Politico; are DailyKos' traffic numbers artificially inflated by Sitemeter?; the lack of social conservatives online; techPresident is profiled by the Washington Post; Leon Wolf leaves the Brownback campaign; Marc Ambinder thinks Chris Dodd's web team is the most innovative out there; Barack Obama and the 21st-century fireside chat; a report from Elizabeth Edwards' meetup with mommy bloggers; and Obama's blog outreach guy leaves the campaign.

Bill O'Reilly may think he's taking on DailyKos with his seemingly daily attacks on the liberal mega-site. But if you look at the numbers, he's doing them a huge favor. Traffic and membership registrations on DailyKos are surging.
