TOPEKA, Kan. (AP) — Four northeast Kansas residents have filed objections to Senator Pat Roberts's candidacy for re-election, arguing the three-term Republican is not truly a Kansas resident. The objections were filed Wednesday by Christine Tawney and Chuck Henderson, of Manhattan, and Tom and Sylda Nichols, of Leonardville. Their complaint will be reviewed by a three-member state board led by the secretary of state. The objections are similar to allegations leveled by Roberts's tea party-backed Republican challenger, Milton Wolf. Roberts owns a home in Alexandria, Virginia, and a duplex unit in Dodge City that he rents out. But Roberts spokesman Leroy Towns says the senator pays income and property taxes in Kansas and has been registered to vote in Dodge City for more than 30 years.
