As the cost of running for president and Congress continues to rise, candidates must ask for more and more money from big donors. A new analysis by the Center for Responsive Politics shows that the top giving industries and interests -- all with major stakes in decisions the new president and Congress will make--are happy to oblige.

While the official reports aren't due at the Federal Election Commission until October 15, candidates are bragging already about the big bucks they are raking in. Hillary Clinton raised $27 million, all but $5 million of it for her primary race. Obama raised $20 million. Congressional candidates are also starting to talk big about their fundraising prowess, as if this is the main thing that matters when running a political race.

The hot campaign news these days is all about small donors recharging the political landscape, and is sure to be part of the story when candidates file their third quarter reports in mid-October. Presidential candidate Sen. Barack Obama (D-IL) already got headlines for breaking records by raising nearly a third of his contributions from donors giving $200 or less.

But make no mistake about it: big donors still dominate.
