14. Sen. James Risch (R-Idaho)

Minimum net worth: $19.69 million

Much of the Idaho senator’s fortune is held in Idaho farm and ranch lands.

Risch owns four tracts of land in Idaho — ranging from 24 acres to about 180 acres — valued at a combined minimum of $16 million.

He also listed other real estate investments, including four investment properties in Boise, valued at $100,000 to $500,000 each. Risch also added a Washington, D.C., condominium to his assets in 2009, valued at $250,000 to $500,000.

Although Risch’s wealth increased in 2009 by about 2 percent, or $400,000, he also added about $380,000 in debts, including a mortgage valued at $250,000 to $500,000. He also disclosed a promissory note issued in 2007 from the Idaho Independent Bank valued at $250,000 to $500,000.
