 -- intro: Deep-pocketed donors are giving an unprecedented amount to this year's campaign, pouring millions into superPACs that support either President Obama or challenger Mitt Romney. Some well-heeled supporters also act as "bundlers," or super-fundraisers, convincing friends and business associates to steer their checks toward the campaign and candidate of their choice.

The "superdonors" converged on Tampa for the Republican National Convention, often arriving via private jet, but most tried to keep a low-profile. ABC News was able to catch up with some of the Republican Party's major backers at lavish private events around Tampa Bay, including a party for members of Romney's "Victory Council -- elite donors, fundraisers and politicians -- aboard a yacht called the Cracker Bay.

While many of the faces at the yacht party were familiar, others were harder to identify. If you can help ABC News identify the partygoers in the pictures that follow, please send an email to superdonors2012@gmail.com, and we'll post the correct answers as updates in the story.

UPDATE: The superdonors on pages two, four and six have been identified.

UPDATE: A reader recognized the man in the picture as Eric Tanenblatt , an Atlanta lawyer who is a national finance co-chair for Romney. Tanenblatt was a "Ranger" for George W. Bush in 2004, meaning he raised at least $200,000 for his reelection effort, and was the Georgia state chair for Romney in 2008. He has known Romney since Romney was governor of Massachusetts and Tanenblatt was the finance chair of the Republican Governors Association in 2004. He also held positions in the George H. W. Bush administration and on the staffs of Sen. Paul Coverdell and Gov. Sonny Perdue, both R.-Georgia, and worked on the Bob Dole and Phil Gramm presidential campaigns in 1996 and the George W. Bush campaign in 2000. Earlier this year he attended the same Utah fundraiser and donor retreat as Ray Washburne, also featured in these photos. Tanenblatt did not immediately respond to a request for comment.

UPDATE: One of our readers identified the man in the picture as Dallas businessman Ray Washburne, a campaign "bundler" for George W. Bush who initially supported Tim Pawlenty in 2012 but has helped Romney raise money in Texas. He attended a retreat for Romney's biggest donors and fundraisers at a Utah resort in June, and told attendees at a party at a Dallas mansion that the party and another event the night earlier were expected to raise $3.5 million. Romney joked to partygoers that Washburne had promised that he and three other Texas bundlers would raise $15 million or Washburne would "write a check for the balance."
