Missouri television commercials are suddenly full of scenes of guns being loaded, prayers being offered and big smiles being smiled. Yes, campaign-advertising season is here.

The four candidates for Missouri's Republican nomination for governor — businessman John Brunner, former Navy SEAL Eric Greitens, former Missouri House Speaker Catherine Hanaway and Lt. Gov. Peter Kinder — all have new campaign ads out this week. Two of them feature firearms. One shows an explosion.

The winner of the Aug. 2 Republican gubernatorial primary will likely face Democratic Attorney General Chris Koster.
