Consider these numbers:

• Nearly half of the members of Congress are millionaires, according to the Center for Responsive Politics (CRP), a Washington watchdog.
• The median net worth of a U.S. senator was $2.63 million in 2010, the most recent year for which financial data are available. That was up 11% from the year before, says CRP.
• The median estimated net worth for House members was $756,765.
• The median net worth of House members almost tripled from 1984 and 2009, while the net worth of Americans declined slightly during the same time, according to the Washington Post and the University of Michigan.

"It's no surprise that so many people grumble about lawmakers being out of touch," said Sheila Krumholz, CRP executive director. And it's not only the news of their costly yachts and expensive vacations that rankles.
