Gov. Sam Brownback has filed for re-election, saying that under his watch Kansas has become a lighthouse for the nation.

Brownback and Lt. Gov. Jeff Colyer filled out the necessary paperwork Thursday morning to ensure that their ticket is on the Aug. 5 Republican primary ballot.

They were joined at the Statehouse event by former U.S. Senate Majority Leader Bob Dole and Mary Jean Eisenhower, a granddaughter of President Dwight Eisenhower.

Dole and Mary Jean Eisenhower are the honorary leaders of Brownback’s re-election campaign.

Brownback touted cuts to income taxes aimed at creating job growth as an example of his first-term leadership.

Brownback faces a primary challenge from Wichita landscaping business owner Jennifer Winn. Kansas House Minority Leader Paul Davis of Lawrence is the only announced Democratic candidate.
