CHICAGO (CBS) — Cash-strapped mayoral hopeful William “Dock” Walls says his campaign is going strong, and getting stronger in race pitting four challengers against Mayor Rahm Emanuel.

Walls, an aide to the late Mayor Harold Washington, has run for mayor twice before, losing to Richard M. Daley in a race less crowded than this one in 2007.

Why does Walls expect the result to be any different this time?

“Daley was popular, and I got 10 percent of the vote in that election,” Walls said.

Four years ago, Walls got less than one percent of the vote in a field of six candidates, including Emanuel.

This year, Walls is one of four challengers running against Emanuel, including Ald. Bob Fioretti, Cook County Commissioner Jesus “Chuy” Garcia, and businessman Willie Wilson.

Walls said Emanuel has made voters angry in his first term.

“Those red light cameras; blue light cameras; speed zone cameras; fines, fees, and assessments; closing 50 schools,” Walls said.

He didn’t deny he’s got the least campaign funding of the five candidates, but he remained undeterred.

“We work harder than the other candidates. We do three to five senior citizen buildings a day. We’re out talking to our 17-and 18-year-olds,” he said.

Walls said he’s getting his word out on the streets, and through his campaign website.

“We have a calendar. It’s on our website, and if you go to that calendar, you’ll see that we’re participating in those. We’re in several of the televised debates,” he said.

All of Walls’ rivals have enough money for TV commercials, so Walls has loaned his campaign $25,000.

“We expect to be on television when it matters most,” he said.

Walls is the guest on this week’s edition of “At Issue,” airing Sunday at 9:30 a.m. and 9:30 p.m.
