Until recently, most polls of the Nevada Senate race showed Republican Joe Heck with a small but consistent lead over Democrat Catherine Cortez Masto. But last week, two Democratic surveys (one from PPP and another from Clarity Campaign Labs) gave Cortez Masto a small edge, though a GOP poll had Heck up 47-44. And now, over the last few days three more polls have dropped, and they show the contest no worse than tied for Team Blue.

A CBS/YouGov poll has the Senate contest deadlocked 39-39, while Hillary Clinton leads Donald Trump 46-40 in the Silver State. However, YouGov says that the undecideds in the Senate race favor Clinton 47-30, so Cortez Masto ought to have more room to grow. Meanwhile, a poll from a Republican pollster, JMC Analytics, conducted for Las Vegas' CBS affiliate, has Cortez Masto up 41-36 as Clinton leads 43-41. Very few polls have shown Cortez Masto running ahead of Clinton, but a CNN/ORC survey finds a similar result as JMC. Their poll has Cortez Masto up 52-45, while Clinton leads just 46-44 with likely voters. - DailyKOS
