Salt Lake County Commissioner Mike Stewart and his old colleague, Republican Tom Shimizu, continue to hold leads over their Democratic challengers, a Dan Jones & Associates poll shows.

In a poll taken the end of July for the Deseret News and KSL-TV, Jones found that Stewart leads Jim Bradley 43-30 percent; 1 percent say they'd vote for someone else, and 25 percent are undecided.Shimizu, who left the commission two years ago to run unsuccessfully for the U.S. House of Representatives, leads Riverton City Mayor Dale Gardiner 55-24 percent, Jones found. Libertarian Gary Root was favored by 2 percent; 19 percent were undecided.

Stewart is running for a third term in the four-year seat. Shimizu held the two-year commission seat before losing to Rep. Wayne Owens, D-Utah, in 1986. That year, Democrat Dave Watson beat Republican Merrill Cook for Shimizu's seat. Cook is running as an independent for governor this year.

Watson planned to seek re-election. But last spring he was arrested for driving under the influence and possession of a controlled substance. He later pleaded guilty to DUI and to a reduced drug charge. Watson dropped out of the race, claiming physical disability caused by the stress of his arrest. Salt Lake County Democratic delegates replaced Watson on the ballot with Gardiner. Watson resigned his commission seat this past week.

In late June, Jones found that Stewart led Bradley 45-31 percent and Shimizu led Gardiner 54-29 percent. So the races haven't changed much over the summer months.
