Political analysts say Johnson's wealth and Fargo's potential ability to raise money could make this year's mayoral contest the most expensive in the city's history.
Johnson is a former Phoenix Suns guard who returned to his hometown after retiring. Since then, he’s tried to redevelop the troubled Oak Park neighborhood.
Fargo was first elected to the city council in 1989, and won her first race for Mayor of Sacramento in 2000. She’s running for a third four-year term.
