TOPEKA, Kan. (AP) — Republican Gov. Sam Brownback says his tough race for re-election is swinging back his way because Democratic challenger Paul Davis hasn’t been visible enough to Kansas voters.

But Davis announced Monday that he’ll make a 30-stop bus tour of the state this week.

Brownback and his wife voted in advance Monday at the Shawnee County Election Commissioner’s office. He told reporters afterward that voters’ doubts about his tenure as governor are easing.

He said part of the reason is that Davis hasn’t defined his views clearly for some voters, and he suggested that Davis has been avoiding public events.

But Davis spokesman Chris Pumpelly said voters remain concerned about Brownback’s fiscal policies and noted that Davis is beginning his bus tour Tuesday.
