Though five men are chiefly responsible for financial and policy decisions governing McLennan County, oftentimes three is the magic number.Commissioners Lester Gibson, Joe Mashek and Kelly Snell have been the driving force behind some major decisions on the court this year, casting the crucial three votes that dictate how the five-member body governs the county.But the 3-2 dynamic is not new to the court. When former commissioner Wendall Crunk held Snell's Precinct 1 seat for 11 years, Crunk, County Judge Jim Lewis and Commissioner Ray Meadows often ruled the vote on major decisions.
