Republican Tucson mayoral candidate Rick Grinnell is shifting his campaign focus now that he's officially on the ballot for the general election.

Grinnell ran a successful write-in campaign during the primary election, earning the GOP nomination for the November city election.

He says his years of involvement on community boards and working with small businesses make him a good candidate to lead the city.

Grinnell faces Democrat Jonathan Rothschild and Green Mary DeCamp in the mayoral race.
