When Barack Obama ran for president in 2008, no major U.S. corporation did more to finance his campaign than Goldman Sachs Group Inc. GS +0.13%
This election, none has done more to help defeat him.
Prompted by what they call regulatory attacks on their business and personal attacks on their character, executives and employees of Goldman Sachs have largely abandoned Mr. Obama and are now the top sources of money to presidential candidate Mitt Romney and the Republican Party.
In the four decades since Congress created the campaign-finance system, no company's employees have switched sides so abruptly, moving from top supporters of one camp to the top of its rival, according to a Wall Street Journal analysis of campaign-finance data compiled by the nonpartisan Center for Responsive Politics.
Employees at Goldman donated more than $1 million to Mr. Obama when he first ran for president. This election, they have given the president's campaign $136,000—less than Mr. Obama has collected from employees of the State Department. The employees have contributed nothing to the leading Democratic super PAC supporting his re-election.
By contrast, Goldman employees have given Mr. Romney's campaign $900,000, plus another $900,000 to the super PAC founded to help him.
