Why he probably won't: Last year, during the government shut down, Arnold and his wife gave $10 million to keep Head Start programs for low income children running while government funds were cut off. Were he looking to segue into the political realm, this would have been the perfect opportunity. Instead, Arnold dodged the spotlight for his major gift.
Why he could: The co-founder and former CEO and chairman of America Online, Case has been one of the most politically active and vocal proponents in the tech community for economic policies that spur innovative job growth. He currently serves on several Presidential committees, including the President's Council on Jobs and Competitiveness. And his family isn't a stranger to politics - a cousin, Ed Case, served as a congressman from Hawaii from 2002 to 2007.
Why he probably won't: Compared to some of the others, Case has one of the most bipartisan donation records among Nader's list. In 2012, he directed campaign cash to high-profile Republicans including House Speaker John Boehner and Florida Sen. Marco Rubio, as well as high-profile Democrats including House Minority Leader Nancy Pelosi and New York Sen. Chuck Schumer. With his money spread around like that, it's likely both parties' establishment folks would work hard to talk him out of an independent run.
Why he could: The world's most profitable hedge fund manager in 2011, the 38-year-old billionaire was declared "the hottest young money manager on the planet" by Forbes last year. Though yet to develop a reputation for being outwardly political, Coleman did serve for six years as co-chairman of the Tiger Foundation, an organization that aims to end poverty in New York City, and has donated money to both the Republican Senatorial Committee and to Mitt Romney during previous election cycles.
