On this installment of ST, we offer the third and final interview in our three-part series of conversations with the leading candidates to be Tulsa's next mayor. As per changes to the City Charter that were enacted in 2011, the current race for mayor will be non-partisan, with a primary scheduled for Tuesday of next week: June 11th. If no candidate receives 50 percent of the vote in this primary, the top two vote-recipients will meet up in the general election, in the fall --- and if any one candidate gets more than 50 percent of the vote in this primary, that person will become our next mayor (to serve a three-year term beginning in early December). Earlier this week, we heard from Kathy Taylor and then Bill Christiansen; on today's edition of StudioTulsa, we hear from the current Mayor of the City of Tulsa, Dewey F. Bartlett, Jr., who was elected to be the city's 39th mayor in November of 2009. Mayor Bartlett has long been an active political figure and oil executive in the Tulsa community; he served on the Tulsa City Council from 1990 to 1994, representing District 9. Mayor Bartlett is also the President of the Keener Oil & Gas Company, a multi-generational family business.
