Excuse me?
The Caucuses are OPEN to all Republicans.
There is little difference between a primary and a caucus - except for the turn out of voters.
Please do not spread misinformation.
True enough, but those caucuses can also be gamed. It is where Orin Hatch ganged up on what should have been a death sentence, unlike the other sitting Senator Bennett who got removed from office through the caucus. Hatch had the benefit of seeing what a caucus loss could do to you at the State Convention, and made sure he had his “people” gang up on the caucuses giving him another six years of bad votes.

The Huffpost article nails the reasons for his loss and the reason we now have Mike Lee as Senator from UT, a far better choice. You have to read way down the article to finally read about his attendance at the various caucuses, but that is how he failed to gain delegates at the Convention.
