Salt Lake City Mayor Ralph Becker's latest campaign ad is a direct attack on his challenger Jackie Biskupski.

The ad features local business leaders and Salt Lake County Mayor Ben McAdams who directly questions Biskupski's fitness for the job.

"With a strong partnership between Salt Lake City and Salt Lake County, we've been able to do amazing things," says McAdams in the spot. "I need a strong partner in Salt Lake City, and I'm not sure Jackie has the vision or leadership to be that partner."

Ouch, indeed.
