I thought so, I was just confused over the poll, which would be pointless since it's among RV rather than delegates if there wasn't a primary.
AFAIK, the GOP Nevada caucus is the same format as the GOP Iowa caucus, which is basically just a straw poll. So if you can poll "likely caucus goers", then you have a good poll. Problem is, caucus turnout is much smaller than turnout would be for a primary. In 2008, all of the Nevada caucus polls were off. Mason-Dixon was the closest, which had a Romney lead of 15 points. His actual margin of victory was 37 points. About 25% of the GOP caucus voters were Mormon, and they went 90+% for Romney, so that was about half his voters right there.
