Chaffetz will now face Democrat Bennion Spencer in the November election. And Ellis will face Democratic treasurer candidate Dick Clark.

In northern Utah, Rep. Glenn Donnelson, R-North Ogden, was booted out, losing to fellow Republican Ryan Wilcox. Donnelson has been the legislative pointman on illegal immigration, running several unsuccessful bills trying to take away in-state college tuition for the children of illegal aliens. A minor flap may have also hurt Donnelson, when his local county Republican Party chairman tried to organize a Donnelson-Wilcox debate, Donnelson declined to attend.

Rep. Paul Neuenschwander, R-Bountiful, lost a close race to fellow Republican Becky Edwards in House District 20.

Out in the Uinta Basin, Republican Kraig Powell beat David Labrum in the open District 54 seat.

And down in Carbon County, Christine Watkins beat fellow Democrat Grady McEvoy — also in an open seat — in the only Democratic state legislative primary.

In Senate District 23, Dan Liljenquist, backed by a number of Republican Party insiders, defeated community activist Ron Mortensen in a seat held by retiring Sen. Dan Eastman, R-Bountiful.

"There is nothing more I could have done. We made our case to the voters and they responded," said a jubilant Chaffetz, the former chief of staff of GOP Gov. Jon Huntsman Jr. "If there was ever a time for change, it was this year."

A new public opinion survey for the Deseret News/KSL-TV by Dan Jones & Associates finds that Cannon was reasonably well-liked by GOP voters in his district, but political independents hold a poor view of the incumbent. Jones found that 46 percent of independents disapproved of the job Cannon was doing, only 38 percent approved. And independents could register as Republicans Tuesday and vote in the closed GOP primary.

Chaffetz ran a lean campaign and was outspent more than six to one by Cannon — $631,000 to $98,000. Cannon also had big-name endorsements from most Republican officeholders. But in the end, money didn't matter and neither did endorsements.

Chaffetz had no campaign headquarters and no paid staff.

"I had more than 1,000 volunteers who worked their hearts out for me," he said. "I'm very proud of them."

Cannon, younger brother of Joe Cannon, the Deseret News editor, will leave office in January after serving 12 years in one of the most Republican House districts in the United States. Because Democrats control the U.S. House, Cannon holds no committee or subcommittee chairmanships, but he is the ranking member of a subcommittee and sits on other committees important to Utah.
