Salt Lake mayoral candidate Ralph Becker holds a double-digit lead over challenger Dave Buhler, a new public opinion survey shows.

The Deseret Morning News/KSL-TV poll conducted by Dan Jones & Associates shows that if the Nov. 6 final election were held today, Becker would be favored by 51 percent of Salt Lake City registered voters; Buhler has 33 percent support. Eleven percent didn't know, while 5 percent mentioned someone else.

That 18 percentage point Becker lead, while not insurmountable, will be a tough hill to climb for Buhler.

The survey of 403 registered voters in the city has a margin of error of plus or minus 5.0 percent. So, even within the ranges of the margin of error, Becker still holds a healthy lead.

While the race is officially nonpartisan — meaning the candidates' political party affiliations will not be on the ballot — the Salt Lake mayor's race has historically carried political party overtones, and the new survey shows this one is no exception.

Becker is a Democrat, the past several years serving as the minority leader in the Utah House of Representatives. His House district takes in the Capitol Hill and Avenues sections of the city.

Buhler is a Republican, having served as a GOP state senator for one four-year term in the 1990s from his Sugar House area. Buhler is an eight-year veteran on the Salt Lake City Council, another officially nonpartisan office.

Salt Lakers have not elected a Republican mayor since 1971.

And Jones found that 62 percent of city voters say that the candidate's political affiliation makes either a "great deal of difference" or "some difference" to them in who they support for mayor this year. Thirty-eight percent said a candidate's political party makes "no difference" to them.

Among Democrats, 85 percent said the candidate's political affiliation makes a difference to them. Sixty-eight percent of Republicans felt the same way.

There are some hard political facts facing Buhler now, as the results of Jones' poll point out.

Thirty-four percent of city voters said they are Democrats. A third said they are political independents. Only a quarter said they are Republicans.

Becker gets 77 percent of the Democratic vote and 39 percent of the independent vote, Jones found. Buhler gets 60 percent of the Republican vote — but Republicans are only 25 percent of all voters. Buhler gets only 18 percent of the independent vote.

Clearly, Buhler is being outgunned on the partisan political level.
