LAS VEGAS (AP) — Nineteen Democrats hoping to be the next president have arrived in Nevada seeking support from labor unions in the early voting state.

They are speaking to roughly 500 union members Saturday at a forum by the American Federation of State, County and Municipal Employees. The public employees union boasts 1.6 million members nationally.

Top contenders such as former Vice President Joe Biden and Sens. Elizabeth Warren, Kamala Harris and Bernie Sanders will be in attendance. Many candidates are hosting other events around Las Vegas as well.

Nevada will be the third state, and the first in the West, where Democratic voters will cast ballots in next year’s primary.

Nevada voters often cite the economy as one of the top concerns they want the next president to address.
