One of the more interesting unresolved questions in the 2016 Senate races is whether Senator Mike Lee, Utah Republican, will face a primary challenger. Some deep-pocketed figures in the state are attempting to recruit a challenger:

[Former Romney finance director] Spencer Zwick told KSL News he wants to see Alex Dunn, president of Vivint Inc., who worked on Romney’s 2002 campaign for governor of Massachusetts and served on his gubernatorial staff, take on Lee in a GOP primary in 2016.
Dunn, a graduate of Brigham Young University, confirmed he’s considering a run against the first-term senator.

Lee hears the footsteps, and is getting prepared. He’s hired Matt Rhoades and America Rising, perhaps the best opposition-research organization on the GOP side. Rhoades, of course, was Romney’s campaign manager in 2012.

“We are excited to join Senator Lee’s team in his re-election effort,” Rhodes said in a statement to NRO. “The Senator is working to unite the Republican Party around common sense solutions and a positive agenda. &Utah needs Mike Lee in the United States Senate, and America Rising, LLC will help ensure his campaign has the tools they need to take on an opponent while the Senator focuses on taking his message directly to the people.”
