Eloise Gomez Reyes, one of four Democrats vying for a highly targeted district in California’s Inland Empire , is kicking off a direct mail campaign this week ahead of the upcoming top-two primary.  

The pair of mail pieces , provided first to CQ Roll Call, are tantamount to an opening bio ad in the 31st District, located east of Los Angeles. They describe the attorney’s background as a field worker who went on to college and later law school.  

Mailers are the most popular form of voter communication in California House contests, as TV airtime often comes at a premium in the major metropolitan media markets of L.A. and San Francisco.

The other Democrats running in the June 3 all-party primary include Redlands Mayor Pete Aguilar, former Rep. Joe Baca and San Bernardino City School Board Trustee Danny Tillman. The Republicans in the race are former Capitol Hill aide Lesli Gooch, political consultant Ryan Downing and veteran Paul Chabot. The two leading vote recipients, regardless of party, advance to the general election in November.  

All are looking to succeed GOP Rep. Gary G. Miller, who announced his retirement earlier this year. It’s perhaps Democrats’ best pickup opportunity in the country, as President Barack Obama carried the district by a 17-point margin in 2012.  

Gomez Reyes is backed by EMILY’s List, a group that backs Democratic women who support abortion rights.  

California’s 31st District is rated Leans Democratic by Rothenberg Political Report/Roll Call.
