The crowded field of Republican candidates seeking Rep. Jerry McNerney's seat was reduced to seven when Jon Del Arroz announced on Wednesday that he was dropping out of the race.
Del Arroz, 27, said in an e-mail that he was ending his campaign because his young son was recently diagnosed with cystic fibrosis.
"At this time in my life, the needs of my son rightfully take precedence," Del Arroz said in a news release. "Samantha and I love Mateo and are going to do everything in our power to make his life fulfilling.
"Running a contested campaign against an incumbent and then serving in Washington so far away from home is not an option that would be fair to my son or my wife, and not one that I would even consider given the circumstance," Del Arroz said.
Del Arroz was in Woodbridge as recently as Sept. 16, when he spoke to the Lodi Republican Women.
