Democrats Lead List of Richest Senators

Of the richest U.S. senators, Democrats fill seven of the top ten slots, according to a study conducted by nonpartisan Center for Responsive Politics.

On the House side, Republicans fill six of the top ten.

Authors of the study said it's impossible to give a precise net worth for members of Congress because their individual assets and liabilities are disclosed in broad ranges. To conduct the study, the Center for Responsive Politics determined a member's minimum net worth and maximum net worth and then calculated an average, which was used to rank the members.

Because the law does not require them to do so, members of Congress don't disclose the value of their homes unless they produce income. As a result, a member's true net worth is likely to be much higher than what gets reported.

"Members of Congress don't make it easy for the public to keep tabs on their personal holdings and any conflicts of interest those holdings present," said Dan Auble, who manages the center's database of lawmakers' financial information.
