In 2011, a City Charter amendment to have non-partisan races passed.  The primary on June 11th, 2013, will be the first non-partisan mayoral election in Tulsa. If a candidate gets over 50% of the votes, even by one vote, that candidate becomes mayor.  Otherwise, the top candidates whose vote percentages add up to over 50% will go to a runoff if there are more than two remaining candidates, or the general election if there are only two remaining candidates.

The top candidates are Dewey BartlettBill Christiansen, and Kathy Taylor,
