19) Austan Goolsbee. The young star from the University of Chicago Graduate School of Business is the cheerful face of centrist, market-friendly policies in the Obama Administration. He's won over conservative critics including George Will despite his own criticisms of supply-side conservative policies. His role as chief economist for the President's Economic Recovery Advisory Board will include helping to fix the financial crisis while keeping up the administrations' pro-market, pro-trade credibility.
20) Rupert Murdoch. He won the battle to buy the Wall Street Journal, and the billionaire News Corp. head continues to oversee a sprawling global empire of media properties. How he'll fare during one of the worst advertising markets in history remains to be seen.
21) Nouriel Roubini. They call him "Dr. Doom." The New York University economist has the right to wear the title as a badge of honor. After correctly predicting the severity of the housing and credit crisis, he's a continually popular source for the latest version of what could still go very wrong in the economy.
22) Maria Bartiromo. Anchor of CNBC's "Closing Bell with Maria Bartiromo" and host and managing editor of the nationally syndicated "Wall Street Journal Report with Maria Bartiromo," she's become the first face of financial news during one of the worst downturns in history.
23) Neil Cavuto. Fox's irascible Neil Cavuto has seen his profile rise as the financial crisis rages and the economy swoons. A familiar face on both the Fox News Channel and Fox Business Network, he's the network's unapologetic free-market voice at a time when defending capitalism has become a tougher sell.
24) Lawrence Kudlow. If Barack Obama makes the case for higher taxes on the rich, you can bet CNBC host Lawrence Kudlow will be taking the other side of that trade as a long-time banner-carrier for the tenets of Reagan's supply-side revolution.
25) Paul Krugman. Arguably America's best-known living economist, Krugman won the 2008 Nobel Prize in economics for his work in international trade. In his more public role as one of the staunchest critics of the Bush Administration, the New York Times columnist and author remains both an unapologetic partisan and a helpful demystifier of complex economics.
