6-Term Congressman Loses Republican Primary in Utah -- Opponent Campaigned Against Him As Not Being Tough Enough on Immigration

From The New York Times:

Representative Chris Cannon, one of the most conservative members of Congress, has lost his bid for a seventh term, defeated in a Republican primary that focused on whether he was conservative enough for Utah’s Third District.

Mr. Cannon became the third incumbent congressman to lose a primary this year, after Wayne T. Gilchrest, a Republican, and Albert R. Wynn, a Democrat, both of Maryland.

The American Conservative Union had said that Mr. Cannon was nearly perfect on its issues in 2007, scoring 96 percent. But Mr. Chaffetz repeatedly attacked him as insufficiently conservative, especially on immigration.
