For whatever reason, Nevada's Democratic caucus this Saturday has received scant attention from public polling firms. Until last week, there hadn't been a publicly released poll of the Dem caucus this year. The one that came out last week, showing a 45-45 tie between Hillary Clinton and Bernie Sanders, was met with considerable skepticism because of who commissioned it: the uberconservative Washington Free Beacon. But today we have new polling from CNN/ORC that shows a similar result: Clinton 48, Sanders 47. Remember, Nevada is the first big test of whether Sanders can demonstrate appeal with a more diverse electorate.
