TOPEKA, Kan. (AP) — Republican Gov. Sam Brownback and his Democratic opponent are campaigning in eastern and south-central Kansas with their tight race in its final week.

Democratic challenger Paul Davis was beginning a 30-stop tour Tuesday morning by meeting and greeting prospective voters on the town square in Iola in southeast Kansas.

Davis planned further stops in the southeast Kansas cities of Independence and Pittsburg before going to Topeka for an evening Statehouse rally with teachers.

Brownback was campaigning with fellow Kansas Republican Sen. Pat Roberts and tea party favorite and Kentucky Sen. Rand Paul.

Their first event Tuesday was at noon at Jabara Airport in Wichita, with rallies in Pittsburg and Overland Park later in the day.

Kansas Republicans are launching a four-day bus tour Wednesday.

The election is Nov. 4.
