The latest Emerson College Poll says former Vice President Joe Biden is the leader in Nevada. Biden is at 30%, Senator Elizabeth Warren of Massachusetts is second at 22%, and Vermont Senator Bernie Sanders in third with 19% support. No other candidate hit ten percent in the poll. But it’s early, and a little over half of those polled say they could change their minds. The poll also indicated all would have a tough fight against Trump, calling the race in Nevada a tossup. A second poll just released by the Mellman Group backs up the findings, giving Biden 29% and Warren 19%. That poll was commissioned by the Nevada Independent.
