Declined to run
The following people were the focus of presidential speculation in past media reports, but ultimately decided not to run as independent candidates.
Laurie Roth, Radio Talk Show Host - Roth announced her candidacy for the American Independent Party in November 2011. She also ran for the nomination of the Constitution Party, but lost at the convention. She withdrew from the American Independent Party race in July, after claiming before that she would run Independent. But she then endorsed Republican nominee Mitt Romney and said that she would try to help America in other ways.
Lou Dobbs, broadcast journalist and commentator, of New Jersey
Ron Paul, U.S. Representative, of Texas and Republican nominee

Jesse Ventura, former Governor of Minnesota
Ralph Nader, attorney, Consumer advocate, and perennial presidential candidate of Connecticut
Michael Bloomberg, Mayor of New York City
Bernie Sanders, Socialist Senator, of Vermont
Howard Schultz, CEO of Starbucks
Americans Elect
No nominee - Americans Elect announced on May 17, 2012 that it would not field a candidate for President, as no candidate garnered enough support in the organization’s online primary to reach its self-imposed threshold for the nomination.
Boston Tea Party
No nominee - the Boston Tea Party dissolved itself on July 22, 2012, citing decline in membership activity.
I should add that the Communist Party USA Endorses Obama for 2012 like they did in 2008.
