The collecting began last year, and the contributions flowed into Tampa Bay incumbent constitutional officers focused winning this fall’s elections and keeping their jobs for four more years. By last week, when qualifying ended, nearly a dozen had raked in close to $900,000, ready to wage war with challengers to their positions as sheriffs, tax collectors, clerks of the circuit court, supervisors of elections and school superintendents. Turns out they don’t need that cash at all. Nine constitutional officers in Hillsborough, Pinellas and Pasco counties are running unopposed in the election cycle this year, meaning they have won by default.
