Sen. Pat Roberts (R-KS) does not have a home in his home state of Kansas and, when he needs an address in the state, uses one that belongs to two donors.
.
According to The New York Times, Roberts, who is facing a primary challenge from tea party favorite Milton Wolf, uses the address of donors C. Duane and Phyllis Ross for voter registration and a place to sleep occasionally when he travels to the state.
.
"I have full access to the recliner," Roberts told the newspaper of the home in Dodge City, Kansas. "Nobody knows the state better than I do."

Roberts and his wife, a real estate broker, own a home in Alexandria, Virginia.
