TOPEKA, Kan. (AP) — Republican Pat Roberts is facing questions about whether he can claim the Kansas town of Dodge City as his home as he seeks a fourth Senate term. Roberts and his wife own a duplex unit there, but it has a tenant. He's registered to vote at another Dodge City address less than half a mile to the south. It's a home belonging to another couple, longtime friends and supporters, where he rents a room and a bathroom for $300 a month. The issue is getting new scrutiny after a New York Times story suggested Roberts was "desperate" to re-establish ties with his home state. Roberts says Kansas has always been his home, but primary challenger Milton Wolf says the issue shows Roberts is a creature of Washington.
