Washington ? Democratic candidate Jim Slattery would see a dramatic cut in his salary if he’s elected to the U.S. Senate this fall.

The former congressman from Topeka earned $585,000 last year working for a major Washington law firm. That’s more than three times what he would earn if he unseats incumbent Republican Sen. Pat Roberts.

The information comes from a personal financial disclosure form filed with the Senate this week. In all, Slattery disclosed assets worth at least $4.2 million and as much as $9.4 million. The forms report assets and liabilities in broad ranges that make it impossible to determine exactly how much a candidate is worth.

Most of those assets are in mutual funds and retirement accounts. He also owns an office building in Topeka worth between $500,000 and $1 million, a farm in Atchison worth $250,000 to $500,000, and two Topeka townhouses worth $100,000-$250,000.

Earlier this year, Roberts disclosed assets worth at least $687,000 and as much as $1.7 million. Most of that is the value of two condominiums in Virginia, a home in Dodge City, Kan., and land in South Carolina.
