1996 congressional election
In 1996, Vargas decided to challenge Filner in the Democratic primary. Vargas wouldn't debate Filner, so the incumbent instead sparred with a life-sized Vargas cardboard cutout. Vargas said he agrees with Filner on "99 percent" of issues. Filner defeated him 55%–45%.

2006 congressional election
In 2006 Vargas decided to challenge Filner for a third time, this time in California's 51st congressional district. Vargas accused Filner of being a part of the culture of corruption of Washington, pointing out that Filner had paid his wife more than $500,000 in campaign funds for consulting services performed from their condominium in Washington. Filner in return argued that Vargas had controversial payments to his brother-in-law, who was a lobbyist for realtors. Filner defeated Vargas 51%–43%, with Danny Ramirez getting 6% of the vote.
Business career (2007–2009)
After leaving the State Assembly in 2006 due to term limits, Vargas took a job with a home, auto and small business insurance company, where he was tasked with creating jobs and outreach in diverse San Diego Communities as part of the company's diversity initiative. Vargas left that job at the end of 2009 to run as a Democratic candidate for the California State Senate.
California State Senate (2010–2013)
2010 election
In 2010 Vargas narrowly won a seat in the California State Senate, 40th District. He defeated Assemblywoman Mary Salas by 22 votes, after recounts in San Diego and Riverside counties. He resigned from the Senate effective January 2, 2013 so that he could take his seat as a Congressman. A special election to fill his seat was held in March 2013.
In 2012 when Filner announced he would retire from Congress to run for Mayor of San Diego, Vargas endorsed him despite their history of bitter rivalry. Vargas then ran for Filner's seat in the 51st district. In the open primary, he ranked first with 46% of the vote. Republican Michael Crimmins ranked second with 20%, Democratic State Senator Denise Moreno Ducheny came in third with 15%, and four other candidates received single digit percentages. In November, he defeated Crimmins 71%–29%.
He and his wife, Adrienne, live in the Golden Hill area of San Diego and have two daughters, Rosa Celina and Helena Jeanne. During the 1999 armed conflict in Kosovo, Vargas welcomed a Kosovar refugee family into his family's home for nearly two years.
