Hillary Rodham Clinton is picking up the endorsement of SMART, a soon-to-be-merged sheet metal, air, rail and transportation workers union.

The Democratic presidential hopeful accepted the endorsement from the 230,000-member union during a gathering in Las Vegas.

Clinton also appeared at a rally with a young Hispanic lawmaker who promised her ground support in the early caucus state of Nevada. The first Hispanic immigrant elected to the state legislature said he'd round up people for door-to-door canvassing immediately after the rally.
