Although this year's House freshmen are sharply divided by ideology, they are united by one striking measure: Many of them are filthy rich. The Center for Responsive Politics found that 60 percent of Senate freshmen and 40 percent of House freshmen were worth $1 million or more. The statistics prove that Congress is populated "overwhelmingly with millionaires and near-millionaires who often own multiple homes," says Dan Eggen at The Washington Post. Here, a look at the numbers behind the congressional millionaires' club:
