The most liberal and conservative CEOs

CEOs are people, too. Or at least they have a range of political views similar to those of ordinary folks.

Corporate money has been flooding into politics since a pair of recent Surpeme Court decisions allowed corporations and wealthy people to make unlimited campaign contributions to groups known as super PACs, which can spend as much money as they want supporting a given candidate or cause. That has raised concerns about country-club conservatives, as CEOs are often caricatured, dominating politics.

But many CEOs defy this conservative stereotype, giving to liberal candidates and causes or donating across the political spectrum for pragmatic business reasons rather than personal ideological ones. To get a picture of how conservative or liberal CEOs really are, Yahoo Finance partnered with Crowdpac, a nonpartisan web site that maps politicians across an ideological spectrum based on how they vote, the political behavior of groups they’re affiliated with and other factors. (A full explanation of the methodology follows at the end of this story.) Crowdpac assigns politicians a numerical score ranging from 10L for extremely liberal to 10C for extremely conservative, with 0 representing somebody who’s perfectly centrist. Among the 2016 presidential candidates, for instance, Bernie Sanders ranks as most liberal with a score of 7.6L, while Rand Paul is most conservative with a score of 10C.

Crowdpac is able to rank donors in a similar way, based on the scores of candidates and groups they donate to. Here are the five most liberal CEOs, according to the firm's rankings:

5. Lloyd Blankfein, Goldman Sachs (GS). Ideology score: 4.9L. That’s right, the Wall Street banker who runs a firm vilified as the “great vampire squid” has liberal leanings. But he doesn’t lean as far left as he used to. Since 2008, Blankfein has donated to both Republicans (Sen. Rob Portman, Sen. Richard Shelby, former House Majority Leader Eric Cantor) and Democrats (Sen. Gary Peters, Rep. Greg Meeks). But Blankfein was more consistently Democratic before the financial crisis, giving to big names such as Hillary Clinton (then a New York senator), Sen. Charles Schumer of New York and former Sen. Chris Dodd of Connecticut. Blankfein’s biggest check, $28,500, went to the Democratic Senatorial Campaign Committee in 2007—a pre-crisis year that may have represented peak bonhomie between Democrats and Wall Street. His donations to both parties have shrunk considerably since then.

It's worth noting that two other Wall Street CEOs -- James Gorman of Morgan Stanley (MS) and Jamie Dimon of J.P. Morgan Chase (JPM) --ranked 6 and 7 among the most liberal CEOs, just behind Blankfein. While it's obviously ironic that money men who gripe relentlessly about Washington overregulating Wall Street tend to be liberal, much of it probably has to do with the region they operate in. Both the city and state of New York are largely represented by Democrats, which means Wall Streeters must donate to the left if they want to support home-state politicians.
