After the New York Times reported that Sen. Pat Roberts, R-Kan., was using the house of some Dodge City donors as his voting residency, Roberts' staff declined to detail how much time he spends in Kansas, according to Washington Examiner columnist Byron York. But an unnamed source gave York information indicating that in 2012 Roberts was in Kansas for all or part of 65 days, York wrote, leaving "151 days in 2012 when the Senate was not meeting and Roberts was not in Kansas." Roberts didn't dispute the numbers, telling York: "I don't measure my service in days. I try to measure it in results." Meanwhile, campaign e-mails from Roberts' tea party challenger in the GOP primary, Leawood radiologist Milton Wolf, now refer to "Pat Roberts (R-VA)." Wolf has his own problems, though, including the Public Policy Polling survey showing that only 29 percent of GOP primary voters are familiar with him.
