ALBUQUERQUE, N.M. -

Former state Sen. Tim Eichenberg is leading in the heated Democratic race for New Mexico treasurer.
    
Unofficial results show Eichenberg over former state Democratic Party Chairman John Wertheim with 52 percent of the vote.
    
The race has been among the most contentious this primary, prompting a call from Democratic Party Chairman Sam Bregman to tone things down.
    
The winner faces Republican Rick Lopez in November.
    
During the campaign, Wertheim ran ads accusing Eichenberg of discriminating against Latinos, women and gays with votes in the Senate and as Bernalillo County treasurer.
    
Eichenberg called those attacks a "smear," and he said his opponent doesn't have the experience for the job.
