Hillary Rodham Clinton and Barack Obama, who are running for president as economic populists, are benefiting handsomely from Wall Street donations, easily surpassing Republican John McCain in campaign contributions from the troubled financial services sector. It is part of a broader fundraising shift toward Democrats, compared to past campaigns when Republicans were the favorites of Wall Street. The flow of campaign cash is a measure of how open-fisted banks and other financial institutions have been to politicians of both parties. Concern is rising that no matter who the Democratic nominee is and who wins in November, Wall Street will have a friend in the White House," said Massie Ritsch of the nonprofit Center for Responsive Politics, which tracks campaign donations. "The door will be open to these big banks." Sen. Clinton of New York is leading the way, bringing in at least $6.29 million from the securities and investment industry, compared with $6.03 million for Sen. Obama of Illinois and $2.59 million for McCain. Those figures include donations from the investment companies' employees and political action committees. The candidates' receipts reflect a broader trend that demonstrates how money follows power in Washington. It suggests that the nation's money managers are betting heavily that either Clinton or Obama will capture the White House and that Democrats will retain control of Congress. "What that Wall Street money means is that few people in Washington, including the leading presidential candidates, say a thing when the government moves to bail out Wall Street before it helps homeowners," said David Sirota, a liberal activist and former congressional aide.
