(KTRS) – Don’t look now, but it looks like it will be a tight race for Missouri Governor.

A new Post-Dispatch poll fins that Eric Greitens has moved into a statistical tie with Attorney General Chris Koster. A recently as a month ago, the Republican outsider trailed Koster by five points.

The tightening could be in part due to increased spending on Greitens’ behalf–the Republican Governors Association has contributed a total of $11.5 into the campaign with half of that coming in the last month.
