President Obama's re-election team today voluntarily released the names of  its top 445 financiers for the 2012 presidential campaign.

Combined, these individuals are responsible for at least one third - or $74.4 million - of the total $220 million raised by Obama and Democrats so far.

These wealthy donors each give the legal maximum to the campaign ($5,000) and the DNC ($30,800) and then get their well-placed friends and colleagues to do the same - a practice known as "bundling."

Supporters who bring in $50,000 or more for Obama earn the "bundler" classification.

Obama added an impressive 94 new bundlers to his list in the fourth quarter - October through December 2011 - surpassing the campaign's stated goal of 400 total for the election cycle.

Among the new names are TV actress Eva Longoria - who has assumed a major role in the campaign's outreach to Hispanics - and American Jewish Congress chairman Jack Rosen, who hosted Obama for a fundraiser at his home late last year.

Longoria has bundled between $200,000-$500,000, while Rosen has netted more than $500,000.

Other familiar names who continue to play an integral role in Obama's high-dollar fundraising include movie mogul Harvey Weinstein, UBS Americas CEO Robert Wolf, Vogue editor in chief Anna Wintour and DreamWorks CEO Jeffrey Katzenberg. All have raised more than half a million dollars apiece.

Former New Jersey Gov. and Goldman Sachs CEO Jon Corzine is also listed as a top-level bundler, although the campaign and DNC said late last year that they would return $70,000 of contributions from Corzine and his wife following a federal investigation into his role at the failed brokerage firm MF Global.

Here's the breakdown of Obama bundlers:

140 bundlers at $50,000-$100,000 each

119 bundlers at $100,000-$200,000 each

125 bundlers at $200,000-$500,000 each

61 bundlers at $500,000+ each

Obama and Democrats collected $68 million in the fourth quarter of 2011, much of it coming in the form of small-dollar contributions. More than half a million supporters donated to Obama's re-election effort, with the average contribution of $55, a campaign official said.

An important footnote: The release of bundler information is voluntary, and Obama is the only presidential candidate to release it in this campaign.  None of the Republicans have released comparable information, breaking with a precedent set by George W. Bush and continued by John McCain.
