CNN has done an analysis of Obama's bundlers ahead of another LGBT fundraiser in L.A. on Wednesday which shows how important gay donors are to the President's campaign:

A CNN analysis of President Obama's biggest fundraisers, known as bundlers, shows that at least 33 — or about one in every 16 bundlers — is openly gay. Together, they have raised at least $8 million for the campaign between January and the end of March.

By contrast, in the same period, bundlers from the television, movie and music industry, some of whom attended a recent high-profile fundraiser hosted by actor George Clooney, raised $6.8 million, according to the Center for Responsive Politics.

Only bundlers who are openly gay were counted in CNN's analysis:

The Washington Post has reported that as many as one in six bundlers supporting Obama are gay. The Advocate Magazine estimates one in five.

Glancing down the names on the bundlers list released by the Obama campaign for the first quarter, it is easy to find people known for their work on behalf of the LGBT community.

Tim Gill, a software entrepreneur who runs a large Colorado-based foundation that backs gay rights projects, has already contributed $672,800 with his partner Scott Miller to the Obama for America campaign. Fred Eychaner, who owns the Chicago-based Newsweb Corp., has donated $1,220,550 so far.

He co-hosted a $35,800-per-person LGBT organized fundraiser for Obama in February. Kathy Levinson, the former president and CEO of the Menlo Park, California-based Etrade, gave $202,150. The LA Gay and Lesbian Center Women's Night named Levinson a "Community Role Model" in 2000. She was instrumental in raising money to stop the anti-same-sex marriage law in California.
