There are currently 11 Republicans in the race.
Trent Staggs is a good conservative but lacks money and name recognition. Orrin Hatch’s kid jumped into the race somewhat recently; he has no legislative record to evaluate but he’s surely no hard-core conservative. State House Speaker Brad Wilson claims to be a conservative but is actually a total squish as is ex-congressman Curtis.
Wilson and Curtis have all the establishment funding and Hatch will probably get a bunch too.
Utah’s next senator is highly unlikely to be a conservative unless things change quite a bit between now and November. Utah is a solid *Republican* state; it is definitely not a *conservative* state and is becoming less so every day.
