Cliff Asness, the founding and managing partner of hedge fund AQR Capital, and Rutgers University professor Susan Feinberg may have irreconcilable differences about two $350 bottles of wine at Washington D.C.'s Bistro Bis, but they once found common ground in the campaign of President Barack Obama. Cliff Asness, and his wife Laurel, each gave Obama $2,300 during his 2008 campaign, according to research by the Center for Responsive Politics. Feinberg, too, was a 2008 Obama campaign donor, giving $1,700 in support of his presidential bid.

Obama was just the second federal-level candidate to earn Feinberg's cash, according to the Center's research. (She also gave a similar amount -- $2,000 -- to Democrat John Kerry during his 2004 presidential bid.) Asness, meanwhile, has donated to scores of politicians and political committees -- including Obama's 2008 rivals then-Sen. Chris Dodd (D-Conn.), then-Sen. Hillary Clinton (D-N.Y.), former Republican New York City Mayor Rudy Giuliani and Sen. John McCain (R-Ariz.).

In all, Asness, along with his wife, Laurel, has contributed about $436,000 to federal candidates and committees over the past two decades, according to the Center's research. Of that sum, 80 percent has benefited Republicans, including $114,500 to the Republican National Committee and $72,100 to the National Republican Senatorial Committee. The pair has also donated $33,500 to the Libertarian National Committee since 2008.
