Washington (CNNMoney.com) - Banks, investment firms and hedge funds are giving millions of dollars more to Republicans, and abandoning the Democrats they had been supporting just a year ago.
The Center for Responsive Politics says the reversal began early this year, as the Senate started crafting tougher rules to crack down on Wall Street, and that it has become more pronounced.
"We noticed a very dramatic shift right around the beginning of this year, which coincided with financial reform," said Dave Levinthal, spokesman for the Center for Responsive Politics. "This is not just a blip at all; this is a major shift in the opposite direction and one that has persisted ever since."
Looking at the top 20 candidates for federal office receiving strong support from financial firms, only six are Democrats, the center found. New York Sens. Kirsten Gillibrand and Charles Schumer top that list - which isn't surprising since they represent a chunk of the financial sector, the center noted.
The rest of the top 20 are Republicans, many seeking Senate seats. Former Hewlett-Packard chief executive Carly Fiorina of California tops the list for Republicans, followed by Dan Coats of Indiana and Marco Rubio of Florida.
