From The New York Times:

Senator Orrin G. Hatch, a six-term Utah Republican, fended off a primary challenge from a Tea Party-backed insurgent candidate on Tuesday, a result that showed the power of money, organization and incumbency to overcome grass-roots anger at the Washington establishment.

Ultimately, voters chose experience over insurgency, sparing Mr. Hatch the same drubbing suffered by Republican incumbents like Richard G. Lugar of Indiana last month and Robert F. Bennett of Utah in 2010, who saw their political careers ended by upstart conservatives.

It is a race he will not run again. On Tuesday, Mr. Hatch reiterated that the coming term would be his last.
