Reporter hat off. Analyzer hat on. Senate race 2010.
First, this is a purely political breakdown, so any accusations that I'm being insensitive — aside from that being completely true — will be ignored. Second, when I'm talking about the Senate race, I'm mostly talking about the GOP nominating convention next year, NOT the primary or general elections. At the convention, if you get 60 percent of 2,000 delegates, you move to the general against whatever punching bag the Dems trot out.
Bob Bennett

This looks like a very good thing for Bennett at first glance.
Shurtleff had to be considered his top challenger based on fundraising, name recognition and campaign savvy. But let's take a closer look: Shurtleff wasn't Jason Chaffetz no matter how much he wanted to be. He wasn't getting traction he needed with party delegates and his baggage was starting to pile up in the press. To make up for a lack of base support, he needed to raise money, lots of it. Unfortunately, it wasn't anywhere near where it needed to be to take on an incumbent senator.
So instead of Bennett facing a fatally flawed front-running challenger next year, he now faces The Unknown. He will have a problem if he faces any one of these three potentials:
Jason Chaffetz

The Man, himself. "He's been in office less than a year," is your first counter, but you know in your heart it doesn't matter. The representative from the 3rd District will never be more popular than he is right now. Delegates adore him, his voting record is unimpeachable among the base because there are no consequences to voting from a purely ideological position when in the minority and from a district that is 70 percent Republican. Oh, and his fundraising machine is primed just in case he needs the cash.
He's in the press all the time. He's been the go-to guy in the GOP on social media matters. "But he's so young, doesn't have the gravitas needed in the Senate," you whisper. No, seriously, you're hilarious.
Mike Lee
Gov. Huntsman's former counsel has been making the rounds with his fireside discussions about the Constitution. He considered a run against Bennett in the early going but eventually decided against it. Despite the fact that the base isn't crazy about Huntsman, Lee has scored huge points on the circuit. Raising money won't be easy, but the well-liked scholar and attorney who clerked for Justice Alito could be a sleeper if he changes his mind and gets back in it.
Fred Lampropoulos
That's right. The CEO of Merit Medical has deep pockets and after a sudden exit from the 2004 governor's race courtesy of Huntsman, may be itching to get back into the ring. Lampropoulos is charismatic, a canny businessman and is well-known to delegates.
But what about...

No, I haven't forgotten the candidates already in the race. The problem is that
Cherilyn Eagar is dangerously close to marginalizing herself. Her statement about Shurtleff dropping out is already drawing fire for being less than sensitive:
"I have put a call into Mr. Shurtleff to express my best wishes to him and his family and am awaiting his reply. I have complete respect for Mr. Shurtleff’s decision and for the fact that he got in early, so that the voters could get to know him. A U.S. Senate race is a serious commitment, one that is not made at the last minute. I sincerely hope we do not see in the future a flurry of candidates getting in and getting out. This is not musical chairs."
She's bringing in Joe the Plumber to stump for her, but it's more a book tour for the guy who became a cause célèbre for 15 minutes last year.
Tim Bridgewater

The Provo resident and longtime political insider was at first viewed by some as someone trying to gently back out of the state GOP chairman race he was never going to win by saying he instead wanted to run for Senate. He could then get his issues out there but never be considered a serious challenger. Bridgewater, a successful businessman by all accounts, is a tough read at this point. He's doing the campaign thing with e-mail blasts and cottage meetings across the state. But I'm going to have to take a pass on this one because I just don't know enough here.
