Now that the three-ring circus of Donald Trump’s endorsement has passed, the real action in Nevada is almost here, as 28 Republican delegates are up for grabs on Saturday in the Silver State.

“I’ve had a lot of trepidation about polling the caucuses in Nevada, Minnesota, and Colorado in the coming week,” said PPP CEO Dean Debnam on the company’s web site.

“Caucuses are particularly hard to poll and for whatever reason the state of Nevada itself is hard to poll,” he added.

Bzzzzzzzzt.

Your answer – no one.
