On the campaign trail, new figures show traditionally Republican business interests are now donating far more money to the two Democratic candidates. According to the Center for Responsive Politics, Senator John McCain has raised just over $13 million from seven major industries that usually favor Republicans. By contrast, Senator Hillary Clinton has raised $27 million, while Senator Barack Obama has raised $22.5 million. The firms surveyed include companies involved in financial services, pharmaceuticals, military contracts, energy and agribusiness. Both Democrats campaigned in Pennsylvania Tuesday. In Philadelphia, Clinton compared her candidacy to challenges faced by the fictional movie character Rocky Balboa.

Sen. Hillary Clinton: “Sen. Obama says he’s getting tired of the campaign. His supporters say they want it to end. Well, could you imagine if Rocky Balboa had gotten halfway up those Art Museum stairs and said, ‘Well, I guess that’s about far enough?’ That’s not the way it works. Let me tell you something, when it comes to finishing the fight, Rocky and I have a lot in common. I never quit. I never give up.”

Senator Barack Obama, meanwhile, set his sights on Republican candidate John McCain.

Sen. Barack Obama: “A few weeks ago, he said that — and I’m quoting here — 'The issue of economics is not something I've understood as well as I should.’ And that’s clear, since all he’s offering is four more years of the same George W. Bush policies that have gotten us into this pickle that we’re in right now.”
