Jim Hosler, a former Hillsborough County planning official, has filed to run against Republican Ken Hagan and Democrat Linda Saul-Sena in the race for the District 5 Hillsborough County Commission seat now held by Jim Norman.
Hosler is running with no party affiliation, saying he doesn't like partisan politics.
Hosler, 57, of Tampa has been a relentless opponent of the county's light-rail proposal, arguing that it's based on flawed ridership and financial projections.
For 18 years, Hosler worked as a director of research and economic development at the Hillsborough County Planning Commission, and says he is familiar with the data behind the rail plans.
"I know that it's cooked," he said.
He has worked as a demographer and economic development consultant in the private sector for the past four years.
The rail discussion, though, isn't the only thing that prompted Hosler to run.
It's also "just the idiocy of the way the board conducts itself," he said.
District 5 is an at-large seat.
