The Center for Responsive Politics has released a preliminary analysis of second quarter campaign finance reports filed earlier this month. All of the nation's congressional candidates raised a total of $168.5 million and spent $73.6 million of that money.

Some interesting findings: On average, Democratic candidates raked in roughly 37 percent more than Republican candidates, $146,858 compared to $106,793. Out of the total amount raised, 77 percent went to currently seated lawmakers.

Legendary rainmaker Sen. Charles Schumer, D-N.Y., raised the most with $3.5 million, he is up for re-election next year. Senate Majority Leader Harry Reid, D-Nev., is a close second having raised $3.3 million.

Stay tuned for the Center's upcoming analysis on what the campaign finance data indicates, including how much the health care industry and finance sectors gave to lawmakers.
