It took Harriette Butler 3 1/2 weeks to file for re-election to the City Council; it took two days for a challenger to emerge. Robert Gupton, a retired Americal production manager who has been active at Speak Up Henderson forums this year, went to the Vance County Board of Elections before 9 this morning and filed to run for Butler’s Ward 2 ward seat. Butler, who faced no opposition two years ago, filed Wednesday. We’ll have more from Gupton about his decision later. Update: Lonnie Davis, who holds the ward seat from Ward 4, filed to run for re-election today.
