The Sanders campaign has begun formal organisational efforts in Nevada, with the hire of a state director.
Political consultant Jim Farrell began working last week as the Nevada state director for Bernie 2016. He was an advisor to former New Mexico governor Bill Richardson.
The hire is the first step to building a formal campaign in Nevada, a state where Clinton has had staff for some months.
Farrell said the campaign will hold a meeting on Saturday in Henderson to organize supporters of Senator Sanders, before the Democratic presidential debate on Tuesday.
He says the campaign also has plans to open offices throughout the state.
Sanders has attracted large crowds of supporters to his rallies in Nevada, notably a 4,500-strong crowd at a rally in Reno.
