"Well-heeled lawmakers like Sen. John Kerry saw paper losses worth tens of millions of dollars.
With the global economic downturn hitting U.S. stock and real-estate markets especially hard in 2008, some of the nation’s wealthiest senators, like their House counterparts, saw steep declines in their personal fortunes last year."

Too bad, so sad, but wait, what about Mitch?
"Senate Minority Leader Mitch McConnell (R-Ky.) and his wife, former Labor Secretary Elaine Chao, received a personal gift from a family member worth between $5 million and $25 million, according to his annual financial disclosure report, which was released on Friday morning.
The gift came from Chao’s father, Dr. James S.C. Chao, a wealthy Chinese-born businessman, and it boosted McConnell’s personal worth from a minimum of $3 million in 2007 to more than $7 million.
“That was a gift from Secretary Chao’s father in April 2008 to the Senator and the Secretary, in memory of her mother, who passed away in August 2007,” said Don Stewart, McConnell’s spokesman. Ruth Mulan Chu was a historian.
Gifts of any value from family members to senators are permitted under Senate ethics rules."
